Abstract
A light emitting device includes: a light emitting element emitting first light; a fluorescent material layer disposed on the light emitting element and excited by the first light to emit second light being longer in wavelength than the first light; a reflective film disposed on the fluorescent material layer to reflect the first light and transmit the second light; a light-transmissive member disposed on the reflective film; and an absorbing layer disposed on the light-transmissive member to absorb the first light.
