An active matrix substrate or TFT substrate is provided with a lower layer wiring with a groove wiring structure covering surroundings of a copper layer with a barrier metal film is formed by forming a groove at an insulating substrate and depositing the barrier metal film and the copper layer in this groove. This groove wiring structure is used for a TFT substrate of a liquid crystal display (LCD) device. It is possible to manufacture an LCD device with large size, high density, a large aperture ratio and in which the disclination defects originating from a different in level of the lower layer wiring and an occurrence of disconnection failures in an upper layer wiring are suppressed.

A liquid crystal display device capable of reducing a disclination region generated when an alignment layer is not normally rubbed due to physical interference between a pattern spacer formed on a substrate and fibers of a rubbing cloth in a rubbing process and a rubbing and fabricating method thereof are disclosed. The liquid crystal display device includes a liquid crystal panel having two bonded substrates with a liquid crystal layer interposed therebetween, alignment layers formed on the two substrates to align liquid crystal molecules in a predetermined direction, and a pattern spacer formed on any one substrate to maintain a distance between the substrates. The alignment layers are rubbed by a rubbing cloth having fibers inclined in a left or right direction with respect to a perpendicular direction of a rotation shaft of a rubbing roll, and the pattern spacer has an inclined surface parallel to the fibers.

The invention provides a reflection type liquid crystal device, and a projection type display and electronic equipment in which display defects caused by disclination are reduced, minimized or prevented from being produced for a highly fine liquid crystal display with a space between pixels made to be narrow to make it possible to provide a high-contrast and bright display. A liquid crystal device includes a liquid crystal layer sandwiched between a first substrate and a second substrate, and a first electrode and a second electrode formed on a face of the above-described second substrate on a side of the above-described liquid crystal layer. The above-described first electrode and the above-described second electrode are formed so that an electric field substantially parallel to the surface of the substrate with respect to the above-described liquid crystal layer can be applied thereto. The above-described first electrode is formed in a linear shape having a specified line width on the above-described second electrode with a second insulation film interposed therebetween. The above-described second electrode is formed in a rectangular shape, and at least one of the above-described first electrode and the above-described second electrode is a reflecting electrode that causes incident light coming from a direction of the above-described first substrate.

The invention provides a thin film transistor (TFT) array substrate, a manufacture method thereof and a display device, which relate to the field of display device manufacture and prevent an electrode slit corner from generating a liquid crystal contrarotation domain and a disclination line so as improve light transmitting rate of the area. The method includes that by changing the shape of a lower-layer electrode, and the slit corner of an upper-layer electrode and the lower-layer electrode do not have corresponding overlapping in the vertical direction so that electric field strength of the area is weakened. An embodiment of the TFT array substrate, the manufacture method and the display device is applied to manufacture of the TFT array substrate.

To provide a technology for fabricating a high image quality liquid crystal display device, a set range of a cell gap for holding a liquid crystal layer is limited in accordance with a distance of a pixel pitch in which specifically, the cell gap is set to be a distance of one tenth of the pixel pitch, whereby the high image quality liquid crystal display device with no occurrence of image display failure caused by disturbances of an electric field such as disclination, can be realized.
