Beschreibung
Zusammenfassung:	A liquid crystal display device includes an array substrate having a switching element, a coupling electrode, an insulating layer, a first pixel electrode electrically connected to the output electrode of the switching element, and a second pixel electrode insulated from the first pixel electrode; a counter substrate facing the array substrate and having a common electrode; and a liquid crystal layer disposed between the array substrate and the counter substrate. The material of the insulating layer is set in order to allow the product of resistance and capacitance formed by the coupling electrode, the insulating layer, and the second pixel electrode to be similar to, within a predetermined range, the product of resistance and capacitance formed by the second pixel electrode, the liquid crystal layer, and the common electrode. Thereby, an afterimage can be reduced. 액정 표시 장치는 스위치 소자, 커플링 전극, 절연층, 스위치 소자의 출력 전극에 전기적으로 연결된 제 1 화소 전극, 제 1 화소 전극과 절연된 제 2 화소 전극을 구비하는 어레이 기판; 상기 어레이 기판과 마주하며, 공통 전극을 구비하는 대향 기판; 어레이 기판과 대향 기판 사이에 배치된 액정층;을 포함한다. 커플링 전극, 절연층, 제 2 화소 전극에 의해 형성되는 저항과 커패시턴스의 곱은 제 2 화소 전극, 액정층, 공통전극에 의해 형성되는 저항, 커패시턴스의 곱이 소정 범위 이내로 유사한 값이 되도록, 절연층의 재질이 설정되며, 이에 의해 잔상이 감소할 수 있다.
