1. A display device comprising
a first electrode,
a pixel define layer disposed on the first electrode, the pixel define layer comprising an opening exposing a portion of the first electrode,
a light emission layer disposed in the opening, the light emission layer in electrical communication with the first electrode through the opening,
a second electrode disposed on the light emission layer,
a light recycle layer disposed on a side of the opening of the pixel define layer, and
a color filter layer disposed on the second electrode, the color filter layer comprising a quantum dot,
wherein the light recycle layer reflects a first light and transmits a third light, and the first light has a different wavelength than the third light.
