Abstract:
1. A light-emitting device comprising: a substrate; an organic electroluminescence device formed on the substrate; a transparent insulation layer formed directly on the organic electroluminescence device; a polarization separator formed directly on the transparent insulation layer; a phase plate formed on the polarization separator; and a polarizer formed on the phase plate, wherein the organic electroluminescence device comprises: wherein the polarization separator reflects a specific light among light traveling from an emissive layer side to a polarization separator side and transmits remaining light, the specific light has a wavelength range that is narrower than a light emission range of the emissive layer, and when converted into linear polarized light by the phase plate, the specific light includes a circular polarized light component to be absorbed by the polarizer, and the first electrode includes a reflective surface for reflecting circular polarized light impinging vertically on the reflective surface as a circular polarized light of which direction of rotation is reversed.
