摘要： A liquid crystal display device includes a display panel having liquid crystal pixels, and a backlight which illuminates the display panel. In particular, this liquid crystal display device further includes a light source driving unit which turns on and off the backlight at a predetermined duty ratio every frame period for update of a video signal, and a panel driving unit which allows each of the liquid crystal pixels to hold a variable pixel voltage that depends on the video signal for a gradation display period longer than a turn-on period of the backlight and which allows each of the liquid crystal pixels to hold a fixed pixel voltage that does not depend on this video signal for a non-gradation display period shorter than a turn-off period of the backlight.
