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.
摘要翻译：以低成本提供可以获得从任何方向观察时具有对比度的明亮图像的反射彩色液晶显示装置。反射彩色液晶显示装置具有内部反射器，并且能够产生具有高对比度的明亮图像，因为可以减少来自非开口部分的不必要的反射光，并且其开口率可以仅基于反射层的间隔来确定和透明电极之间的间隔。这可以通过去除对应于黑矩阵层的反射层，向在反射层下方具有突起和凹陷的聚合物层添加黑矩阵功能，并且使其元素的组成使得不形成黑矩阵层在反射层上，但仅形成滤色器。
