Patent ID: 8198804

Claim:
A display device comprising a plurality of pixels placed in a matrix form, each of the pixels comprising a light emitting device wherein the light emitting device comprises: a light emissive layer configured to emit light; a reflective electrode, disposed on a rear surface side of the light emissive layer, configured to serve as a light reflective plane and an electrode; a transparent electrode disposed on a front surface side of the light emissive layer; a dividing wall, disposed between the reflective electrode and the light emissive layer at a periphery part of a region where the reflective electrode is formed, covering a part of the reflective electrode; a protective layer on a front surface side of the transparent electrode, wherein a sum thickness of the transparent electrode and the protective layer is no greater than a quarter of a wavelength of the light emitted by the light emissive layer; and a transparent substrate disposed above the protective layer; wherein the protective layer and the transparent substrate are spaced from one another so as to delimit a space where a gas is sealed.
