Abstract:
A light emitting device includes: a light emitting element configured to emit first light; 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, and a lateral surface that meets the upper surface, the first wavelength conversion member being configured to emit second light when excited by the first light; a second wavelength conversion member covering the lateral surface of the first wavelength conversion member without covering the upper surface of the first wavelength conversion member, the second wavelength conversion member having an oblique surface extending outward from the lateral surface of the first wavelength conversion member, the second wavelength conversion member being configured to emit third light when excited by at least one of the first light and the second light; and a first light reflecting member covering the oblique surface.
