Abstract

본 발명은 신규한 구성의 FLCD를 개시한다.The present invention discloses a FLCD of novel construction.

자발분극에 의한 쌍안정 특성에 의해 매우 빠른 응답을 보이는 강유전성 액정은 배향이 곤란하고 안정되지 못하는 문제가 있었으며, 이를 해결한 SSFLCD는 미세한 셀갭을 요구하여 제작이 곤란함에도 역시 배향이 안정되지 못하는 문제가 있었다.Ferroelectric liquid crystals that exhibit very fast response due to bistable characteristics due to spontaneous polarization have a problem that alignment is difficult and unstable, and the SSFLCD which solves this problem requires a fine cell gap, which makes it difficult to manufacture even when manufacturing is difficult. there was.

본 발명에서는 강유전성 액정을 종래의 수평배향 대신 용이한 수직배향으로 정렬하고 프린지 필드에 의해 이를 구동하도록 함으로써 큰 셀갭에서도 안정된 특성을 나타내도록 하였다.In the present invention, the ferroelectric liquid crystal is aligned in an easy vertical alignment instead of the conventional horizontal alignment and driven by a fringe field, thereby exhibiting stable characteristics even in a large cell gap.
