Abstract:
A light emitting device includes: a substrate; a light emitting element disposed on the substrate; a first wavelength conversion member disposed on the light emitting element and having a lower surface bonded to the light emitting element, an upper surface opposite the lower surface, and a lateral surface that meets the upper surface; a first light reflecting member disposed on an upper surface of the substrate and covering lateral surfaces of the light emitting element; and a second wavelength conversion member disposed on the first light reflecting member, on the upper surface of the substrate, and on the lateral surface of the first wavelength conversion member without covering the upper surface of the first wavelength conversion member.
