ABSTRACT:
A light-emitting device which is manufactured by a simple manufacturing method and which efficiently extracts light emitted from an emissive layer outward to improve the light extraction efficiency. The light-emitting device comprises a first electrode, a second electrode and an emissive layer disposed between them and extracts a part of light emitted from the emissive layer as radiated light. In this light-emitting device, the first electrode, the nano-structure layer for extracting the radiated light, and a gap having a refractive index lower than an average refractive index of the emissive layer and a nano-structure layer, are arranged in that order in a direction in which the radiated light is extracted.
