Abstract:
A light emitting device includes: a substrate; a light emitting element disposed on the substrate, the light emitting element having an upper surface and a lateral surface; a reflecting layer located on the upper surface of the light emitting element; a first light-transmissive member having a first surface in contact with the lateral surface of the light emitting element, and a second surface that is inclined toward the substrate in a direction outward from the light emitting element; and a second light-transmissive member in contact with the second surface and covering the light emitting element. A refractive index of the first light-transmissive is smaller than a refractive index of the second light-transmissive member.
