Abstract

액정의 유전율이방성 및 게이트트랜스터의 리크전류가 표시에 주는 영향으로 실질적으로 제거한다.
단형의 하소어레이(1)와, 이를 구동하는 드라이버(2,3)를 구비한 액티브매트릭스 액정 디스플레이에 있어서, 각 화소(4)에 액정표시소자(9)에 출력이 접속되도록 유니티게인을 갖는 버퍼앰프(11)를 설치한다. 앰프(11)의 입력은 그 화소의 홀드커패시터(5)에 접속되며, 또한 직렬로 접속된 게이트트랜지스터(6a,6b) 에도 접속된다. 트랜지스터(6a)의 게이트는 대응하는 스캔전극(8)에 접속된ㄴ다. 트랜지스터(6a,6b)는 데이타전극(7)과 앰프(11)의 입력 사이에 직렬로 접속된다. 앰프(11)의 출력은 트랜지스터(6a.6b) 사이의 접속부에 접속된다.
