Abstract:
A light-emitting device includes a substrate and a light-emitting element formed on the substrate. The light-emitting element includes a stacked layer structure portion including a reflective electrode, a light-emitting layer on the reflective electrode and a transparent electrode on the light-emitting layer which are stacked over the substrate with the reflective electrode as a bottom layer, the light-emitting layer having a flat surface provided at least on a portion of the light-emitting layer. A bank is disposed in a peripheral area surrounding the flat surface or on a peripheral portion of the flat surface and has a tilt surface tilted with respect to the flat surface. A conductive film is at least provided on the tilt surface and is electrically connected with the transparent electrode, and forms a reflective surface on the tilt surface, and an optical waveguide layer is provided in an area surrounded by the tilt surface.
