Claim 18:
19. The light emitting device of claim 18, wherein the reflective layer and the second electrode form a micro cavity having a resonance wavelength,
wherein the organic emission layer is configured to emit visible light comprising light of a first wavelength and light of a second wavelength,
wherein the first wavelength is λ, a diameter of each of the plurality of nanostructures of the reflective layer, a height of each of the plurality of nanostructures, and a period of the plurality of nanostructures are determined such that an optical length of the micro cavity satisfies nλ/2, where n is a natural number, and
wherein a diameter of each of the plurality of recesses is determined such that the plurality of recesses are configured to absorb the light of the second wavelength.
