Abstract

본 발명은 TFT 액정표시소자의 저장 축전기의 공통전극(9)의 모양과 구동방법에 관한 것이다.The present invention relates to a shape and a driving method of a common electrode 9 of a storage capacitor of a TFT liquid crystal display element.

종래에는 화소전극(1)과 신호선(4) 사이에 투명도전막인 단일 ITO막을 입혀 저장 축전기에 공통전극으로 썼다. 그리고 이러한 방법은 저장축전기의 공통전극이 단일막이기 때문에 어느 한 곳에서라도 단락된다면 화소 전체에 영향을 받는다. 또한 저장 축전기의 다른 배선들 사이의 기생용량 때문에 생기는 신호지연과 신호 왜곡으로 화질이 떨어진다.Conventionally, a single ITO film, which is a transparent conductive film, is coated between the pixel electrode 1 and the signal line 4 to be used as a common electrode in a storage capacitor. In this method, since the common electrode of the storage capacitor is a single film, if the short circuit occurs at any one location, the entire pixel is affected. In addition, image quality is degraded due to signal delay and signal distortion caused by parasitic capacitance between different wires of the storage capacitor.
