1. A display device comprising:
a pixel unit including first pixels disposed in a first pixel area and second pixels disposed in a second pixel area; and
a controller configured to correct grayscales of a first image data corresponding to the first pixel area based on a dimming level defining a maximum luminance at which the pixel unit is able to emit light,
the controller is configured to supply data signals to the pixel unit based on the corrected first image data and second image data corresponding to the second pixel area;
a luminance of the first pixel is lower than a luminance of the second pixel responding to input grayscales in a first grayscale range; and
a number of the first pixels disposed per unit area is less than a number of the second pixels disposed per unit area.
