Abstract:
A light emitting device includes a light emitting element, a light transmissive member, and a cover member. The light transmissive member is disposed on an upper face of the light emitting element. The cover member covers a lateral face of the light emitting element and a lateral face of the light transmissive member, and includes first and second cover members. The first cover member is disposed adjacent to the lateral face of the light emitting element and the lateral face of the light transmissive member, and contains a first light reflecting material and a fluorine-based first resin. The second cover member covers the first cover member, and contains a second light reflecting material and a second resin. A refractive index difference between the first light reflecting material and the first resin is larger than a refractive index difference between the second light reflecting material and the second resin.
