Claim Text:
1. An active matrix-type liquid crystal display device, comprising: a liquid crystal panel configured such that sub-pixels constituting color pixels are arranged two-dimensionally; an adjacent gradation correcting unit configured to correct gradations of the sub-pixels included in a video signal; and a drive circuit configured to drive the liquid crystal panel based on a video signal after correction obtained by the adjacent gradation correcting unit, wherein when the adjacent gradation correcting unit determines a gradation of a target sub-pixel corresponds to a liquid crystal application voltage is higher than for 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 unit performs correction processing to the video signal for correcting the gradation of the adjacent sub-pixel so as to make the gradation difference smaller, each of the sub-pixels has a long side and a short side, and the adjacent gradation correcting unit performs the correction processing taking two sub-pixels disposed adjacent on the short side out of four sub-pixels disposed around the target sub-pixel as the adjacent sub-pixel.
