Liquid crystal device and display apparatus having a pair of electrodes with a vertical alignment film in which the chiral pitch length to gap ratio (P/G) is 0.06 to less than 1.0 |
摘要 |
A liquid crystal device comprises a first alignment surface which induces a high pretilt greater than 45° but less than 90°; a typical value is 85°. The pretilt has a component parallel to the surface pointing in a predetermined direction. A second alignment surface induces a low pretilt which is less than 45° but greater than 0°; a typical pretilt is 5°. The low pretilt has a component parallel to the second surface which also points in the predetermined direction. A layer of crystal material is disposed in between the first and second surfaces. A novel liquid crystal mode is thus provided and is referred to as the “splay-twist mode”. Such a device may be used in a switchable public/private display. |
