Abstract:
A light emitting device includes a substrate; a semiconductor light emitting element provided on the substrate; a mirror that is formed on the substrate and reflects light emitted by the semiconductor light emitting element; a first resin disposed apart from the semiconductor light emitting element on an optical path and containing a light diffusing material; and a second resin disposed on the optical path between the semiconductor light emitting element and the low light diffusion portion and covering a light emitting surface of the semiconductor light emitting element at least in a region in which a density of the light is highest. A concentration of a light diffusing material in the second resin is lower than a concentration of the light diffusing material in the first resin.
