FERROELECTRIC LIQUID-CRYSTAL DISPLAY

Key technologies for the tau-Vmin mode FLCDs (Ferroelectric Liquid Cry stal Displays) were developed. An FLC material with negative dielectri c anisotropy was developed, realizing fast line address time of 23 mu sec/line at 25. The C2-uniform (C2U) orientation with chevron layer st ructure was achieved by using an aligning film with medium pretilt ang le. High shock stability (20kg/cm(2)) was achieved by making a spacer wall structure within display. Combining these key technologies with d igital gray scale method (2 bits spatial dither and 3 bits temporal di ther), a 6 ''-prototype color FLCD with 240x320 dots, 262,000 colors ( 64 gray levels for each color) was fabricated.
