Abstract: According to an aspect, a display device includes a display panel comprising a plurality of pixels, a light guide plate, a light source configured to emit light from a lateral side of the light guide plate, a dimming panel, and a controller. The dimming panel comprises a plurality of dimming areas arranged in an emission direction of the light from the light source. The dimming areas are capable of individually changing transmittance of the light according to intensities of light required to display an image using the display panel. When adjacent two of the dimming areas differ in light transmittance from each other, the controller increases output gradation values of target pixels, the target pixels being located in a predetermined area extending from a boundary between the two dimming areas in one of the two dimming areas that has lower light transmittance.
