Claim 17:
18. A light emitting device comprising:
a reflective layer comprising a plurality of nanostructures that are periodically two-dimensionally arranged;
a planarization layer disposed on the reflective layer;
a first electrode disposed on the planarization layer;
an organic emission layer disposed on the first electrode; and
a second electrode disposed on the organic emission layer,
wherein the planarization layer comprises a conductive material that is transparent with respect to light emitted by the organic emission layer,
wherein the planarization layer is disposed on upper surfaces of the plurality of nano structures such that an air gap is provided between adjacent nanostructures of the plurality of nanostructures,
wherein the reflective layer further comprises a base,
wherein the plurality of nanostructures protrude toward the planarization layer from an upper surface of the base, and
wherein the reflective layer further comprises a plurality of recesses that are recessed from the upper surface of the base and two-dimensionally provided.
