Abstract: According to an aspect, a display device includes a display unit, an illumination unit, a measurement unit, and a control unit. When pixels that are expected to perform display output at identical luminance are adjacent to each other in adjacent partial regions, and when a difference in the intensity of the internal light between light emitting regions corresponding to the adjacent partial regions is equal to or larger than a predetermined threshold, the control unit performs correction to increase luminance of a predetermined number of pixels belonging to a first partial region corresponding to a first light emitting region the intensity of the internal light from which is lower among the adjacent partial regions. The predetermined number of pixels are located closer to a second partial region corresponding to a second light emitting region the intensity of the internal light from which is higher among the adjacent partial regions.
