A display device includes: first dummy pixels including a self-emission element emitting first color light corresponding to emission colors of pixels in a display area; second dummy pixels including a self-emission element emitting the first color light and a self-emission element emitting second color light and causing both self-emission elements to emit light at the same time; a deterioration degree calculating unit calculating a deterioration degree in brightness of the self-emission element emitting the first color light on the basis of a brightness detection result of the first dummy pixels and calculating a deterioration degree in current flowing in the self-emission element emitting the first color light on the basis of brightness detection results of the first and second dummy pixels; and a correction unit correcting the brightness of effective pixels contributing to an image display on the basis of the deterioration degree in brightness and the deterioration degree in current calculated by the deterioration degree calculating unit.
