Abstract:
A liquid crystal display device includes a liquid crystal panel, a backlight panel and a backlight drive circuit which outputs drive current of the backlights, the duty ratio and the amplitude of which are changeable. The backlight drive circuit outputs the drive current based on duty ratio characteristics that the duty ratio is greater as the luminance of the backlights is higher and amplitude characteristics that is divided with a predetermined luminance as a boundary into the first and second regions, and that the change rate of the amplitude of the drive current with respect to the luminance is less than or equal to the predetermined change rate in the first region, and the change rate of the amplitude of the drive current with respect to the luminance is greater than the predetermined change rate.
