Problems solved by technology

[0007] As described above, in the conventional viewing angle control, since the viewing angle control panel including the viewing angle control liquid crystal element is provided, the liquid crystal display device may become heavy and thick.
[0008] In addition, in conventional viewing angle control, the effective aperture ratio may decrease due to the display panel having pixels for viewing angle control.

no. 1 Embodiment approach ）

[0039] In this embodiment mode, a normally black (normally black) liquid crystal display device including initially vertically aligned liquid crystals or initially horizontally aligned liquid crystals will be described. In this embodiment, the structure of a sub-pixel unit will be described. However, the same configuration as that of the present embodiment can also be applied in units of pixels.

[0040] figure 1 It is a partial cross-sectional view showing an example of the liquid crystal display device of the present embodiment. Should figure 1 It is a cross-section perpendicular to the comb-tooth axis of the comb-tooth-shaped (for example, strip-shaped) electrode. exist figure 1 In the figure, the operation of the liquid crystals L1 to L14 caused by the liquid crystal display substrate 2 and the array substrate 3 and the oblique light 8 realized by the operation are shown. in the figure 1 In , illustration of vertical alignment film, polarizing plate, retardation plat...

no. 2 Embodiment approach ）

[0100] In this embodiment, examples of various materials such as transparent resins and organic pigments used in the liquid crystal display substrate 2 of the first embodiment described above will be described.

[0101]

[0102] The photosensitive coloring composition used for forming a light-shielding layer or a colored layer contains, in addition to a pigment dispersion, a polyfunctional monomer, a photosensitive resin or a non-photosensitive resin, a polymerization initiator, a solvent, and the like. The highly transparent organic resin used in this embodiment, such as a photosensitive resin or a non-photosensitive resin, is called a transparent resin.

[0103] Transparent resins include thermoplastic resins, thermosetting resins, or photosensitive resins. As thermoplastic resins, for example: butyral resin, styrene-maleic acid copolymer, chlorinated polyethylene, chlorinated polypropylene, polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polyvinyl acetate, pol...

Abstract

A liquid crystal display substrate, the purpose of which is to prevent a liquid crystal display device from becoming heavy and thick, to prevent a reduction in the aperture ratio, and to perform effective field-of-vision control, and to do so by realizing effective visual control without using a vision controlling element or vision controlling pixels. The liquid crystal display substrate comprises polygonal pixels and polygonal sub-pixels, and a linear pattern (7). In a planar view, the polygonal pixels and the polygonal sub-pixels have parallel opposing sides, and the linear pattern (7) is provided on the parallel opposing sides of the polygonal pixels or the polygonal sub-pixels. Oblique light (8) passes through the linear pattern (7).

Description

technical field [0001] Embodiments of the present invention relate to a substrate for a liquid crystal display and a liquid crystal display device including the substrate for a liquid crystal display. Background technique [0002] In recent years, the weight of electronic equipment using liquid crystal display devices has gradually decreased, and opportunities for information equipment such as mobile phones and mobile PCs to be used in public places have increased. When using an information device in a public place, confidential information or private information displayed on the liquid crystal display device may be seen by other people around. [0003] When displaying confidential information or private information on a liquid crystal display device in a public place, it is desirable that the liquid crystal display device has a narrow field of view. When many people view information displayed on a liquid crystal display device, it is desirable that the liquid crystal displ...
