Abstract

A light emitting apparatus includes a first light emitting element for a first color and a second light emitting element for a second color whose wavelength is shorter than the wavelength of the first color. The first light emitting element includes a first reflection layer, a first transparent insulating layer, a first transparent electrode layer, a first light emitting layer, and a first upper electrode layer in this order. The second light emitting element includes a second reflection layer, a second transparent electrode layer, a second light emitting layer, and a second upper electrode layer in this order. The second reflection layer and the second transparent electrode layer are in contact with each other.
