Abstract:
1. A light emitting apparatus comprising: a substrate; multiple light emitting devices formed on the substrate, each of the multiple light emitting devices comprising: a reflective layer; a first electrode; a functional layer including an emission layer with an emission region; and a second electrode; and an optical waveguide which is formed between the emission regions and comprises a periodic structure, wherein the optical waveguide has an optical distance in a direction perpendicular to a surface of the substrate, which is smaller than twice an optical distance of each of the emission regions in the direction perpendicular to the surface of the substrate, and wherein the optical distance of the optical waveguide in the direction perpendicular to the surface of the substrate is 3/8 times or more to 11/8 times or less a light emission peak wavelength λ of the emission layer.
