    Abstract: A display device include a light-emitting panel having first to third light-emitting diodes and a color panel on the light-emitting panel. The color panel includes first to third color areas that transmit light of different colors and a light-blocking area. The light-emitting panel includes two first power lines spaced apart from each other, connecting electrodes electrically connected to the two first power lines, and an insulating layer on the connecting electrodes, the insulating layer having openings each of which exposing a respective one of the connecting electrodes. The first light-emitting diode, the second light-emitting diode, and the third light-emitting diode are spaced apart from one another between the two first power lines. The second color area is smaller than each of the first color area and the third color area in size. The second color area is disposed between the first color area and the third color area.
