Abstract:
A light emitting device includes a light emitting element including a first surface; a light guide member covering at least a part of a lateral surface of the light emitting element; a first wavelength conversion member covering the first surface and including a first wavelength conversion particles; and a reflective member being in contact with the light emitting element. The first wavelength conversion member has a thickness of 60 μm or more and 120 μm or less. The first wavelength conversion particles have an average particle size of 4 μm or longer and 12 μm or smaller; the first wavelength conversion particles have a central particle size of 4 μm or longer and 12 μm or smaller. A weight ratio of the first wavelength conversion particles is 60% by weight or more and 75% by weight or less with respect to the total weight of the first wavelength conversion member.
