To provide a liquid crystal display device which performs pseudo impulsive driving, ensures brightness of a screen, and can improve the contrast of the screen. An arithmetic device for generating insertion images is provided in a liquid crystal display device for realizing pseudo impulsive driving. A moving object region and a background region are extracted from first image data which is input to the arithmetic device; second image data where the moving object region is displayed as a black image or a white image is generated; and a display panel performs display where the second image data of nth frame is displayed as an insertion image in a period between the first image data of nth frame and the first image data of (n+1)th frame.
