Abstract:
A light-emitting device includes a base, a light-emitting element, a wavelength conversion member, and a light reflecting member. The base has a base upper surface. The light-emitting element is provided on the base and includes a semiconductor layer, a light transmissive substrate, and a recess. The semiconductor layer is provided on the base so that a semiconductor lower surface faces the base upper surface of the base. The light transmissive substrate has a substrate upper surface, a substrate lower surface opposite to the substrate upper surface, and a substrate side surface between the substrate upper surface and the substrate lower surface. The light transmissive substrate is provided on the semiconductor layer so that the substrate lower surface contacts a semiconductor upper surface of the semiconductor layer. The recess is provided on the substrate upper surface of the light transmissive substrate. The wavelength conversion member is provided in the recess.
