Abstract:
A light-emitting element includes a light transmissive substrate, a semiconductor layered body, and first and second light reflecting members. The semiconductor layered body is formed on a first main surface of the light transmissive substrate. The first light reflecting member covers a first lateral surface, a second lateral surface, a fourth lateral surface, and a second main surface of the light transmissive substrate. The second light reflecting member covers a surface of the semiconductor layered body that is opposite from a surface on which the light transmissive substrate is disposed. A cross-sectional plane of the light transmissive substrate parallel to the first main surface has a concave figure that includes a recess, and the third lateral surface includes one or more surfaces defining the recess.
