Abstract: According to an aspect, a display device includes: a display panel having a display area including pixels; a light source device configured to emit light from an emission area overlapping the display area toward the display panel; a dimming panel between the display panel and the light source device and configured to adjust brightness of emission light emitted from the emission area; and a drive circuit configured to drive the dimming panel. The emission area has a first emission area and a second emission area. The drive circuit is configured to, when gradation values of first pixels corresponding to the first emission area are equal to gradation values of second pixels corresponding to the second emission area, make transmittance of a second dimming area corresponding to the second pixels higher than that of a first dimming area corresponding to the first pixels in the dimming area.
