To further improve light extraction efficiency, a light-emitting apparatus includes a cavity for resonating light emitted from a emission layer between a first reflective surface and a second reflective surface. The first reflective surface is located on a first electrode side relative to the emission layer. The second reflective surface is located on a second electrode side relative to the emission layer. A periodic structure for extracting, to outside of a light-emitting device, light which is generated from the emission layer and wave-guided in an in-plane direction of the light-emitting device between the first reflective surface and the second reflective surface is formed in the first reflective surface, or in the second reflective surface, or between the first reflective surface and the second reflective surface. |
