摘　　要：N*-Sc*相变序铁电液晶器件具有半"V"字形电光特性,可实现连续灰度,并且自发极化值小、视角宽、响应时间为毫秒量级,适合TFT-LCD。控制分子层排列是获得良好器件性能的关键。深入分析了电场对分子层排列的影响,提出了分子层排列模型,为提高器件性能提供了有益的参考。Ferroelectric liquid crystal cell with a chircal nematic-chircal smectic C （N^＊-Sc^＊ ） phase sequence can obtain continuous gray scale, which has the half “V” shaped electro--optical characteristics. It is suitable for TFT-LCD because of the small spontaneous polarization, wide view angle and microsecond fast response. Controlling the molecular layer alignment is the key of achieving the high quality cell. The influence of the electric field on molecular layer alignment was analyzed in depth. And the molecular layer alignment model was proposed.
