A light emitting device includes a light emitting element emitting an excitation light and a fluorescent element. The fluorescent element includes a semi-translucent film facing the light emitting element, and transmits the excitation light; a first luminescent film including phosphors to absorb the excitation light transmitted through the semi-translucent film and to emit a visible light having a different wavelength than the excitation light; and a reflection film disposed on an opposite side of the first luminescent film on which the semi-translucent film is disposed, reflecting the excitation light transmitted through the first luminescent film towards the first luminescent film.
