Abstract:
A light emitting device includes a light emitting element, a light guide member, a reflecting member, a wavelength conversion member. The light emitting element has a light emitting surface and lateral surfaces. The light guiding member is provided on at least a portion of the lateral surfaces of the light emitting element. The reflecting member is provided on the lateral surface of the light emitting element with the light guiding member interposed therebetween. The wavelength conversion member is provided on the light emitting surface of the light emitting element, the light guiding member and the reflecting member. The wavelength conversion member is provided with a recess between an outer lateral surface of the wavelength conversion member and the light guiding member. The reflecting member is provided in the recess.
