Patent ID: 7768196

Claim:
A top emission organic EL light-emitting device formed on a substrate, emitting light from the side opposite the substrate, the organic EL light-emitting device comprising: a light reflection layer over the substrate; a first electrode made of a transparent conductive material over the light reflection layer; a function layer disposed on the first electrode and including an organic EL luminescent layer that emits light; a second electrode disposed on the function layer and including a semi-transparent semi-reflective layer that transmits part of the light emitted from the organic EL luminescent layer and reflects the rest of the light; and a dielectric mirror disposed between the function layer and the light reflection layer, the dielectric mirror acting as an optical resonator that strengthens light having a specific wavelength, wherein the dielectric mirror is formed by alternately forming at least one low-refractive-index material layer and at least one high-refractive-index material layer on the light reflection layer, and wherein the first electrode constitutes one of the at least one high refractive index material layer.
