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.

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.
