Classification: CPC H | IPC H

Claim 0:
1. A display device, comprising:
a substrate including a first light emitting region;
an anode electrode disposed on the substrate, the anode electrode overlapping the first light emitting region;
a layer on the anode electrode, the layer including a first light emitting layer, a second light emitting layer overlapping the first light emitting layer, and a third light emitting layer overlapping the first light emitting layer and the second light emitting layer;
a cathode electrode on the layer;
a wavelength conversion pattern on cathode electrode, overlapping the first light emitting region and wavelength-converting blue light into green light;
a first color filter on the wavelength conversion pattern; and
a first refractive layer between the wavelength conversion pattern and the first color filter, wherein
any one of the first light emitting layer, the second light emitting layer, and the third light emitting layer emits green light,
other two of the first light emitting layer, the second light emitting layer, and the third light emitting layer emit blue light, and
the wavelength conversion pattern comprises quantum dots and scatterers.
