Abstract: A display device includes a light emitting element; a color conversion layer that absorbs light emitted from the light emitting element and emits one of first color light, second color light, and third color light; a color filter layer that allows light emitted from the color conversion layer to selectively pass through the color filter layer; and an intermediate layer disposed between the color conversion layer and the color filter layer, that reflects a portion of the third color light to the color conversion layer, and transmits portions of the first and second color light to the color filter layer. The intermediate layer includes first, second, third, fourth and fifth layers. Each of the first, third, and fifth layers include a conductive material. Each of the second and fourth layers include a material different from that of the first, third, and fifth layers.
