Abstract
A liquid crystal display device is configured so that one frame is divided into two fields and a pixel of a liquid crystal panel is driven. The liquid crystal display device performs overdrive when a gray-scale level to be supplied to the pixel is different between a previous frame and a current frame. The liquid crystal display writes a voltage corresponding to the gray-scale level of the pixel with a positive voltage in a first field, and writes a voltage corresponding to the gray-scale level to be supplied to the pixel with a negative voltage in a second field. When performing overdrive, the liquid crystal display device performs overdrive in both of the first field and the second field. Also, when performing overdrive, the liquid crystal display device corrects the gray-scale level to be supplied to the pixel.
