Abstract

[목적] 시야각 의존성을 억제하고, 표시품위를 향상시킨다.
[구성] 한쪽 기판(16)에 형성된 복수개의 평행한 선상전극부(18)를 가진 제1전극(22)과, 그 각 선상전극부간에 배치된 복수개의 평행한 선상전극부를 가진 제2전극(28)과, 스위칭소자(30)를 가지고, 배향막의 프레틸트각이 3° 이하이고, 배향막의 배향방향()과, 선성전극부의 세로방향이 평행하고, 전극간격(G)과, 양기판의 간격(D)이 다음식을 만족한다.
0.5≤G／D≤3.0
[효과] 전계의 변화에 의하여 액정을 기립시키거나 또는 가로눕히는 것이 아니기 때문에 액정의 긴축방향과 짧은 축방향의 굴절율의 차이에 의한 투과율의 저하가 발생하기 어렵게 되고, 시야각 의존성이 억제되어 표시품위가 향상한다.
