Provided is a display panel, a source driver that generates a gradation voltage signal based on an image data signal, a timing controller that supplies the image data signal to the source driver, and an illumination drive unit that controls an amount of light of a backlight that illuminates each of a plurality of areas formed by dividing a display screen in the display panel. The source driver or the timing controller calculates feature values of the image data signal corresponding to each of the plurality of areas of the display panel and supplies a dimming data signal representing the amount of light of the backlight according to the feature values of each area to the illumination drive unit. The illumination drive unit controls the amount of light of the backlight for each of the plurality of areas based on the dimming data signal.
