Abstract:
Provided is a light emitting apparatus in which light extraction efficiency can be improved without adversely affecting a functional layer of a light emitting device. The light emitting apparatus includes multiple light emitting devices formed on a substrate, each of the multiple light emitting devices at least including: a reflective layer; a first electrode; the functional layer including an emission layer with an emission region; and a second electrode. In which an optical waveguide including a periodic structure is formed between the emission regions and the optical waveguide includes a surface which is opposite to the substrate and is more repellent to a light emitting material liquid for forming the emission layer than the emission region.
