Patent ID: 8304977

Claim:
A light emitting device comprising: a light emitting element having a first electrode layer, a second electrode layer, and a light emitting functional layer disposed between the first electrode layer and the second electrode layer above a substrate; a reflection layer which is disposed between the substrate and the first electrode layer and reflects light emitted by the light emitting functional layer toward the light emitting functional layer; a semi-transparent semi-reflective layer which is disposed above the light emitting functional layer and reflects a portion of light emitted by the light emitting functional layer toward the light emitting functional layer, and transmits the other portion of the light; and a reflection enhancing layer which is disposed on the semi-transparent semi-reflective layer and includes a first layer having a refractive index higher than a refractive index of the semi-transparent semi-reflective layer, wherein the first layer is in contact with the semi-transparent semi-reflective layer.
