LIGHT-EMITTING APPARATUS
First Claim
1. A light-emitting apparatus comprising:
- a substrate; and
a light-emitting device formed on the substrate, the light-emitting device comprising;
a first electrode formed on the substrate;
an insulating member covering a periphery of the first electrode;
a functional layer formed on an exposed portion of the first electrode and comprising an emission layer; and
a second electrode formed on the functional layer and the insulating member,wherein 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.
