ABSTRACT:
A liquid crystal display device includes a liquid crystal display panel DP in which liquid crystal pixels PX are connected to a source line X via pixel switching elements, and a display control circuit CNT which performs non-video signal writing for driving the source line X according to a non-video signal and applying the potential of the source line X to one of the liquid crystal pixels PX via a selected one of the pixel switching elements T and performs video signal writing for driving the source line X according to a video signal and applying the potential of the source line X to one of the liquid crystal pixels PX via a selected one of the pixel switching elements T. The display control circuit CNT is configured to provide a precharge period between a non-video signal writing period in which the non-video signal writing is performed and a video signal writing period in which video signal writing is initially performed after the non-video signal writing and transition the potential of the source line X to a level which is close to an intermediate gradation display level corresponding to a video signal in the precharge period.
