Abstract:
The display device includes a first organic electroluminescence element which includes an anode and a cathode which form a pair, and a light emitting layer which is formed between the anode and the cathode on a substrate. The light emitting layer includes a plurality of sub-light emitting layers which perform light emitting of colors which are respectively different. Each of the plurality of sub-light emitting layers is doped with a quantum dot light emitting material corresponding to a color to be emitted. A current with current density corresponding to a position of a sub-light emitting layer of a desired color among the plurality of sub-light emitting layers is injected to the light emitting layer, and the sub-light emitting layer of the desired color performs light emitting.
