ABSTRACT:
A light emitting device has a plurality of light emitting elements each having a first electrode layer, a second electrode layer, and a light emitting layer disposed between the first and the second electrode layers, a reflective layer being disposed between a substrate and the first electrode layer and reflecting light emitted by the light emitting layer to the light emitting layer, the light emitting elements including a red light emitting element that emits a red light, a green light emitting element that emits a green light, and a blue light emitting element that emits a blue light, the green and the blue light emitting elements each having a resonator structure which contains the reflective layer and a translucent half-reflective layer and which is constituted by adjustment of the optical distance between the reflective layer and the translucent half-reflective layer, the red light emitting element not having the resonator structure.
