A resin material having a small relative dielectric constant is used as a layer insulation film 114. The resin material has a flat surface. A black matrix or masking film for thin film transistors is formed thereon using a metal material. Such a configuration prevents the problem of a capacity generated between the masking film and a thin film transistor.

The present invention relates to a photosensitive composition comprising a triazine-based photoactive compound containing oxime ester. The photosensitive composition according to the present invention has good sensitivity, retention rate, mechanical strength, heat resistance, chemical resistance and developing durability since it contains, as photopolymerization initiator, a compound having an oxime ester group and a triazine group in one molecule and thus effectively absorbs UV radiation. Therefore, the photosensitive composition according to the present invention is advantageous not only in curing of materials for color filters, resin black matrixes, column spacers, overcoats and passivation films of liquid crystal displays, but also in high temperature process characteristics.

A tiled display device is formed from display tiles having picture element (pixel) positions defined up to the edge of the tiles. Each pixel position has an organic light-emitting diode (OLED) active area which occupies approximately 25 percent of the pixel area. Each tile includes a memory which stores display data, and pixel driving circuitry which controls the scanning and illumination of the pixels on the tile. The pixel driving circuitry is located on the back side of the tile and connections to pixel electrodes on the front side of the tile are made by vias which pass through portions of selected ones of the pixel areas which are not occupied by the active pixel material. The tiles are to formed in two parts, an electronics section and a display section. Each of these parts includes connecting pads which cover several pixel positions. Each connecting pad makes an electrical connection to only one row electrode or column electrode. The connecting pads on the display section are electrically connected and physically joined to corresponding connecting pads on the electronics section to form a complete tile. Each tile has a glass substrate on the front of the tile. Black matrix lines are formed on the front of the glass substrate and the tiles are joined by mullions which have the same appearance as the black-matrix lines. Alternatively, the black matrix lines may be formed on the inside surface of an optical integrating plate and the tiles may be affixed to the integrating plate such that the edges of the joined tiles are covered by the black-matrix lines. A cathodoluminescent tile structure is formed from individual tiles that have multiple phosphor areas, a single emissive cathode and horizontal and vertical electrostatic deflecting grids which deflect the electron beam produced by the single cathode onto multiple ones of the phosphor areas.

Reflective color filters using layers of cholesteric liquid crystals with two different center wavelengths and bandwidths per layer are stacked in two layers to provide colored light for displays. With a two layer stack circularly polarized light of one handedness can be provided. With a two layer stack circulary unpolarized colored light can be provided. With a broadband polarizing filter overlapping other filters in the stack a black matrix can be provided by reflecting all colors and transmitting no light in the overlapping areas. When broadband reflective cholesteric liquid crystals are used two primary colors can be reflected in the same pixel of a display making reflective layers with two reflective portions per layer possible. Color displays having three linear sub-pixels with three primary colors or with four sub-pixels of white, blue, green, and red in a pixel with two colors in a top row and two colors on a bottom row can are made with two colors per layer in two layer stacks. The pixels in the display are arranged such that multiple adjacent sub-pixels in a layer, or row in a layer, with the same color makes the color filters easier to manufacture. Displays using these reflective color filters may have a reflective polarizer for viewing the display at wide angles without color distortion.

A liquid crystal display (LCD) having a built-in touch screen panel includes a first substrate having a plurality of pixels, wherein each of the pixels comprises a thin film transistor and a pixel electrode; a plurality of common electrode patterns corresponding to the pixel electrodes and spaced from each other along a second direction; a second substrate facing the first substrate, the second substrate having color filter patterns, wherein the color filter patterns are arranged to correspond to the pixels; a plurality of black matrix patterns between the color filter patterns, the plurality of black matrix patterns being spaced from each other along a first direction crossing the second direction; and a liquid crystal layer between the first and second substrates, wherein the plurality of common electrode patterns and at least one of the black matrix patterns are used as driving electrodes and sensing electrodes, respectively.

A liquid crystal display panel includes a counter substrate having a counter electrode and a multi-layered dielectric film both formed thereon, and an array substrate formed with pixel electrodes and thin-film transistors serving as switching elements. A layer of polymer dispersed liquid crystal material containing a UV-curable resin component and a liquid crystal component is sandwiched and sealed between the counter and array substrates. A light shielding film is formed over each thin-film transistor. The multi-layered dielectric film is a laminated structure of alternating thin-films of SiO2 and HfO2. Since the multi-layered dielectric film is of a nature capable of transmitting UV-rays of light therethrough, the UV-curable resin component positioned underneath the multi-layered dielectric film can be cured during the manufacture. Also, since the multi-layered dielectric film is of a nature capable of reflecting light of a visible region, it serves as a black matrix, reflecting the visible light modulated by the display panel. Black beads are used to keep the film thickness of the liquid crystal layer at a predetermined value. Preferably, a dielectric thin-film having a relative dielectric constant smaller than that of the liquid crystal material is formed on signal lines for transmitting signals to the thin-film transistors, to thereby accomplish an electromagnetic shield. Where color filters are to be formed on the pixel electrodes, those color filters may be formed on the signal lines to accomplish the electromagnetic shield.

In a liquid crystal display (10) having a curved display surface, long sides of pixel structures (11) are arranged along the curve direction (Y) of the display surface and on a side of counter substrate provided is a black matrix having a black matrix opening (41a) whose length in the curve direction (Y) is not longer than E−L {(T1 / 2)+(T2 / 2)+d} / R, assuming that the length of the display surface in the curve direction (Y) is L, the thickness of an array substrate is T1, the thickness of the counter substrate is T2, the size of the gap between the array substrate and the counter substrate is d, the radius of curvature of the curved display surface is R and the length of a long side of a pixel electrode (29) provided in each of the pixel structures (11) is E. It thereby becomes possible to suppress display unevenness resulting from positional misalignment of the two substrates due to curvature and provide a liquid crystal display achieving a high-quality display image.

An in-plane switching mode active matrix type liquid crystal display device includes a first substrate, a second substrate located opposing the first substrate, and a liquid crystal layer sandwiched between the first and second substrates. The first substrate includes a thin film transistor, a pixel electrode each associated to a pixel to be driven, a common electrode to which a reference voltage is applied, data lines, a scanning line, and common electrode lines. Molecular axes of liquid crystal are rotated in a plane parallel with the first substrate by an electric field substantially parallel with a plane of the first substrate to thereby display certain images. The common electrode is composed of transparent material, and are formed on a layer located closer to the liquid crystal layer than the data lines. The common electrode entirely overlaps the data lines except an area where the data lines are located in the vicinity of the scanning line. The liquid crystal display device further includes a light-impermeable layer in an area where the common electrode entirely overlaps the data lines. The light-impermeable layer is comprised of a black matrix layer having a width smaller than a width of the common electrode.
