Abstract

본 발명은 액티브 매트릭스 액정표시장치의 상부 판넬 제조방법에 관한 것으로 상부 판넬의 공통 전극층 하부 판넬의 박막 트랜지스터의 위치에 수직적으로 상응하는 부분을 제거하여 공통전극을 패턴을 형성함으로써 하부 판넬의 회소전극에 인가된 전압 감소를 지연시켜 전압 왜곡 현상을 방지하도록 하여, 액정표시장치의 고화질의 영상을 실현할 수 있다.The present invention relates to a method for manufacturing an upper panel of an active matrix liquid crystal display device. By delaying the applied voltage reduction to prevent the voltage distortion phenomenon, it is possible to realize a high quality image of the liquid crystal display device.
