ABSTRACT:
A light-emitting device is disclosed with improved luminance even with increased arrangement density of a reflector regardless of a light-emitting region. The disclosed device includes a reflector between an electrode for extracting light from a layer including a luminescent material, which serves as a light-emitting region of a light-emitting element, and an exterior space (air). In addition, a light-extraction efficiency can be improved by setting an angle made by a surface of the reflector, which faces the light-emitting element, and a side surface of the reflector (hereinafter, referred to as a slope angle of the reflector) in a predetermined range as for a shape of the reflector.
