Abstract
Fringe-field-switching (FFS) devices using liquid-crystal (LC) with a negative dielectric anisotropy exhibit high transmittance and wide viewing angle simultaneously. Recently, we have developed an "Ultra-FFS" thin-film-transistor (TFT) LCD using LC with a positive dielectric anisotropy that exhibits high transmittance, is color-shift free, has a high-contrast ratio in a wide range, experiences no crosstalk and has a fast response time of 25 msec. In this paper, the device concept is discussed, and, in addition, the pressure-resistant characteristics of the devices compared with that of the twisted-nematic (TN) LCD is discussed.
