ABSTRACT:
A light emitting device includes: a light emitting element which includes a first electrode layer, a second electrode layer, and a light emitting function layer disposed between the first electrode and the second electrode; a reflection layer which reflects light emitted from the light emitting function layer toward the light emitting function layer; and a translucent transflective layer which is disposed opposite the reflection layer with the light emitting function layer interposed therebetween to reflect some of the light emitted from the light emitting function layer toward the light emitting function layer and to transmit the remainder of the light. The translucent transflective layer is centered between a first layer having a refractive index n1and being disposed on a side of the reflection layer and a second layer having a refractive index n2(where n2<n1) and being disposed opposite the first layer.
