Abstract: A display device includes a substrate in which a plurality of sub pixels including an emission area and a circuit area is defined. The display device further includes a storage capacitor disposed in the circuit area and including a first capacitor electrode and a second capacitor electrode on the first capacitor electrode. The display device further includes a driving transistor disposed in the circuit area. The display device further includes a light emitting diode disposed in each of the plurality of sub pixels. The plurality of sub pixels includes a red sub pixel, a green sub pixel, a blue sub pixel, and a white sub pixel. And a distance between the first capacitor electrode and the second capacitor electrode in the white sub pixel is smaller than a distance between the first capacitor electrode and the second capacitor electrode in the red sub pixel, the green sub pixel, and the blue sub pixel.
