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 semi-reflection 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, wherein the translucent semi-reflection layer has a refractive index of 1 or more.
