According to a popularization of LCD-TVs, realization of highperformance moving image LCD, such as field sequential color LCD, is required. This paper points out that we have clarified the temperature dependency of viscosity coefficients and flow effects that are great relevance to response of LC comparing among OCB, ECB and VA modes.From mentioned results, we have designed and realized the high-speed response prototyped OCBmode field sequential color TFT-LCD of 15-inch XGA in consideration of temperature dependency.

A color‐field sequential LCD using a high contrast OCB mode liquid crystal and a LED back‐light has been developed. We established an evaluation method for a polymerized discotic material compensation film and an optimization method for a bend alignment LC cell. The prototype of OCB mode LCD has a high contrast ratio of 1350:1 and wide viewing angle over 170deg. In this paper, the concept of optical compensation and fundamental characteristic of advanced color‐field sequential OCB mode LCD is discussed.
