flu00fcssigkristallanzeigeelement of reflexionstyps and flu00fcssigkristallanzeigeeinheit

摘要

PROBLEM TO BE SOLVED: To provide a reflection type liquid crystal display element and a liquid crystal display wherein generation of alignment defects caused by the structure of pixel grooves and peculiar to a vertical alignment liquid crystal is eliminated or reduced as much as possible and high contrast and satisfactory image quality can be realized.;SOLUTION: A reflection type pixel electrode 42 has a shape whose outer periphery is inclined and such a trapezoidal shape widened toward the end that its electrode width is widened from an upper side toward a lower side. Liquid crystal molecules aligned in extremely horizontal direction in a pixel groove part can be eliminated by forming the side surface of the reflection type pixel electrode 42 in a inclined shape to eliminate vertical properties in its sectional surface. Even if the alignment of the liquid crystal molecules is locally disturbed slightly in the horizontal direction, sufficient vertical properties can be maintained also in the pixel groove part by the interaction with the vertically aligned liquid crystal molecules on the periphery thereof.;COPYRIGHT: (C)2004,JPO&NCIPI
