Abstract
An adjacent gradation correcting unitperforms processing for correcting gradations of sub-pixels to a video signal Xafter overshoot processing. When determining that a gradation of a target sub-pixel corresponds to a higher liquid crystal application voltage than that of a gradation of an adjacent sub-pixel, and that a gradation difference between the target sub-pixel and the adjacent sub-pixel is large, the adjacent gradation correcting unitcorrects the gradation of the adjacent sub-pixel so as to make the gradation difference smaller. In driving a liquid crystal panel, a video signal Xafter correction obtained by the adjacent gradation correcting unitis used. With this, when displaying a specific color, such as red, green, or blue, it is possible to suppress a lateral electric field occurring between two sub-pixels that are adjacent to each other, and to improve response speed of the liquid crystal panel
