摘要： A liquid crystal display device having superior moving-image display characteristics are provided. In the liquid crystal display device, the timing of application of grayscale voltage to liquid crystal cells at the top end of its screen with respect to the timing of application of grayscale voltage to liquid crystal cells in the center of the screen and the timing of application of grayscale voltage to liquid crystal cells at the bottom end of the screen with respect to the timing of application of grayscale voltage to the liquid crystal cells in the center of the screen are made approximately coincident with each other or are deviated from each other by approximately one scanning-line selection period, and a liquid crystal panel is illuminated by a backlight which is intermittently lit in synchronism with vertical synchronizing signals.
