摘要： Provided is a display device with which a suitable image can be displayed with a simple device configuration. The display device has: a display panel which displays an image on the basis of a plurality of image patterns; a plurality of light sources which illuminate, from the back surface, respective regions of the display panel that has been divided into a plurality of regions; a storage unit which stores luminance information in which the respective image patterns and the luminance of the respective light sources in the image pattern are associated with each other; and a luminance control unit which controls the luminance of each of the light sources on the basis of the luminance information. The luminance control unit gradually changes the luminance of the light sources from the luminance of the light source before a change to the luminance of the light source after the change.
