More Information
Summary:PURPOSE: To provide a liquid crystal display device capable of displaying excellently in a sharp contrast even if the liquid crystal display device is increased in precision. CONSTITUTION: In a display matrix whereon pixels connected in series with scanning wiring, TFT main circuits controlled by voltages applied to sub- scanning wiring and display electrodes and main scanning wiring and sub- scanning, signal wiring, and display electrodes are arranged in the serieal direction, and the sub-scanning wiring are arranged in the vertical direction, the above propose is realized by selectively driving the lines by using main scanning pulses sequentially shifted within a frame time for the main scanning wiring, and using sub-scanning pulses varying in a state within the duration of the main scanning pulses for the sub-scanning wiring commonly connected with each other. 본 발명은 액정 표시 장치를 고밀도화하여도 높은 콘트라스트로 양호한 표시가 가능한 액정 표시 장치를 제공하기 위한 것이다. 주사 배선과, 부 주사 배선 및 표시 전극과 주 주사 배선 및 부 주사 배선의 인가 전압에 의해 제어되는 TFT의 주 회로와, 신호 배선과, 표시 전극을 직렬로 접속한 픽셀을 배열하고, 부 주사 배선을 상하 방향으로 배치한 표시 매트릭스에 있어서, 주 주사 배선에 프레임 시간 내에 순차 시프트하는 주 주사 펄스와, 상호 공통 접속된 부 주사 배선에, 주 주사 펄스의 시간 내에 상태가 변하는 부 주사 펄스를 사용하여 라인을 선택 구동함으로써 상기 목적을 달성한다.
