According to an aspect, a display device includes an image display panel; a planar light source including a light guide plate, a first sidelight light source, and a second sidelight light source; and a control unit. The control unit sets first luminance determination blocks in a first display surface of the image display panel and identifies a first luminance determination block to be a target of luminance correction by referring to luminance information on the light sources. The control unit sets second luminance determination blocks in a second display surface of the image display panel and identifies a second luminance determination block to be a target of luminance correction by referring to the luminance information on the light sources. The control unit controls light source lighting amounts of the respective light sources to satisfy luminance of the identified first luminance determination block and the identified second luminance determination block.
