23.1: Fast‐Switching LCD with Multi‐Domain Vertical Alignment Driven by an Oblique Electric Field

Abstract

Abstract We have developed a novel fast‐switching LCD with multidomain vertical alignment driven by an oblique electric field. The oblique electric field is applied between comb‐shaped source electrodes and comb‐shaped common electrodes on a TFT substrate and an ITO electrode on a CF substrate covering the entire display area. The ITO electrode is covered by a dielectric layer. The LCD has a wide viewing range (>160°), a high contrast ratio (>250:1) and fast response times even in black‐and‐white (13 ms (rise), 4 ms (decay)), and gray‐scale (<17 ms) switching. The LCD has no problems with electrostatic charge, disclination, or slow gray‐scale switching.
