ABSTRACT:
Provided is a light-emitting apparatus which can improve the light extraction efficiency without adversely influencing a functional layer of a light-emitting device and which includes a substrate; a light-emitting device formed on the substrate, the light-emitting device including: a first electrode formed on the substrate; an insulating member covering a periphery of the first electrode; and a functional layer formed on an exposed portion of the first electrode and including an emission layer; and a second electrode formed on the functional layer and the insulating member, in which a periodic structure is formed on a surface of the insulating member opposite to a substrate side, and an optical waveguide is formed between a bottom portion of the periodic structure and the first electrode or between the bottom portion of the periodic structure and the substrate.
