A light-emitting unit (121) is provided with a plurality of light-emitting areas that individually emit illumination light, and illuminates a liquid crystal panel (110) with the illumination light from the plurality of light-emitting areas. A motion detection unit (150) detects image motion from an image signal.

An LED driver (122) drives each of the plurality of light-emitting areas in accordance with the determined light emission brightness value for each of the light-emitting areas. The brightness control unit (130) dynamically sets the light-emitting areas that constitute the weighting areas in accordance with the detected motion.
