In the present invention, disclosed is a liquid crystal display apparatus including a gate driver. More specifically, the present invention relates to a liquid crystal display apparatus including a gate driver which reduces the number of a signal wiring increased by overlapped driving a gate driving signal in a high resolution large scale liquid crystal display apparatus. According to an embodiment of the present invention, the liquid crystal display apparatus sets to synchronize a high level section of the gate driving signal not only at rising edge, but also at falling edge on a particular control signal from a gate signal in a gate overlapped driving method, thereby reducing the number of the gate control signal. 본 발명은 게이트 구동부를 포함하는 액정표시장치를 개시한다. 보다 상세하게는, 본 발명은 고해상도 대면적 액정표시장치에서 게이트 구동신호를 중첩구동함에 따라 증가하는 신호배선의 개수를 저감한 게이트 구동부를 포함하는 액정표시장치에 관한 것이다. 본 발명의 실시예에 따른 액정표시장치는, 게이트 중첩구동방식에서 게이트 제어신호 중, 특정 제어신호에 대하여 라이징 에지(rising edge) 뿐만 아니라, 폴링 에지(falling edge)에도 게이트 구동신호의 하이레벨구간을 동기화 하도록 설정함으로써 게이트 제어신호의 개수를 저감할 수 있는 효과가 있다.
