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.

We have developed a new MVA-LCD with fast gray-scale response characteristics. The newly designed jagged shaped pixel electrodes give the oblique electric field and effectively control the LC alignment not only statically but also dynamically. We have realized the response time of 30ms (1/3 of the conventional MVA) for any gray-scale switching keeping other advantageous characteristics same; CR, viewing range etc..
