Abstract

본 발명의 능동 매트릭스형 액정 디스플레이 장치는 다수의 액정 엘리먼트를 갖는다. 각 액정 멜러먼트는 트랜지스터부, 상기 트랜지스터부에 전기적으로 접속된 트랜지스터측 도전성 차광막(116), 및 트랜지스터측에 결합된 대향 전극(121)을 가진 액정 엘리먼트를 갖고 있다. 각 액정 엘리먼트에는 상기 대향 전극(121)에 접속된 제1전위 단자 및 상기 트랜지스터측 도전성 차광막(116)에 접속된 제2전위 단자가 있는데, 상기 제1전위단자에 의해 인가된 전위(Vcom)는 제2전위 단자에 의해 인가된 전위(Vsc)와 다르게 되어 있다. 이러한 배열로 인하여, 액정의 역전 경사의 원인이 되는 화소 부분 주위의 측면 필드 성분이 수직 필드 성분에 비하여 상대적으로 감소되어 디스클리네이션이 감소되고 잔상없이 우수한 디스플레이 특성을 제공할 수 있다.
