摘要： In one pixel, a stepped difference portion having an inclination degree a/b is formed on an alignment control layer, the alignment control layer is made of a material in which a liquid crystal alignment capability is given according to a polarization light radiation, and according to the polarization light radiation the liquid crystal alignment capability is added in the vicinity of the stepped difference portion. A thick and transparent organic high molecular layer is interposed between the alignment control layer and a substrate and a close adhesion characteristic and a transparency characteristic can be made compatible therewith. Accordingly, a problem in which the manufacturing margin in an alignment processing is narrow can be solved, and generation of a display failure according to a fluctuation in the initial alignment direction can be reduced. In this way, a large size liquid crystal display apparatus having a high quality and in which the contrast ratio is heightened can be provided.

摘要： A reflective color liquid crystal display apparatus, which can obtain bright images with a contrast in when viewed from any direction, is provided at a low cost. The reflective color liquid crystal display apparatus has an inside reflector and is able to produce bright images with a high contrast because unnecessary reflecting light from non-aperture portions can be decreased, and its aperture ratio can be determined approximately only by intervals of the reflective layer and intervals between the transparent electrodes. This can be accomplished by removing a reflective layer corresponding to black a matrix layer, adding a black matrix function to a polymer layer having protrusions and depressions under the reflective layer, and making a composition of its element so that a black matrix layer is not formed on the reflective layer, but only color filters are formed.

One of the counter electrodes of the individual pixels is positioned at opposite sides of the video signal line, and the black matrix is formed over the video signal line. The black matrix has a widthwise contour which extends at least as far as the counter electrodes positioned adjacent to the opposite sides of the video signal line.

摘要： A liquid crystal display device including a liquid crystal composition layer having twistable liquid crystal molecules, a first substrate and a second substrate having the liquid crystal composition layer disposed therebetween, a video signal line formed on a face of the first substrate. At least one pixel electrode is fed with a video signal through the video signal line, and at least one counter electrode fed with a counter voltage, the pixel electrode and the counter electrode being opposed to each other. The twisting extent of the liquid crystal moles is controlled by an electric field component which is generated between the pixel electrode and the counter electrode. A spacing between the pixel electrode and the counter electrode arranged to oppose each other is larger than a width of at least one of the pixel electrode and the counter electrode and smaller than a spacing between the pixel electrode and the video signal line.
