Abstract: The present disclosure relates to a display device and a method of driving the same. The display device includes a substrate, a display panel including a first display area including first pixels, a second display area including second pixels, and a third display area disposed between the first and second display areas and including third pixels, and a component disposed between the substrate and the display panel so as to overlap the second display area. Transmittance of the second display area is higher than transmittance of the first display area and transmittance of the third display area, and the third pixels are controlled such that a luminance gradually changes according to a distance from the second display area.
