Abstract
A display device includes: a pixel unit including a first area including first pixels disposed with a first density and a second area including second pixels disposed with a second density smaller than the first density; a power supply for supplying a first power voltage commonly supplied to cathodes of first light emitting elements of the first pixels; and a second-power voltage setting unit for setting a magnitude of a second power voltage commonly supplied to cathodes of second light emitting elements of the second pixels. When the pixel unit displays a black image, the second-power voltage setting unit sets the second power voltage to be higher than the first power voltage.
