Abstract:
A light emitting device according to one embodiment of the present disclosure includes a light emitting element, a fluorescent material layer, a reflective film, a light-transmissive member, and an absorbing layer. The light emitting element emits first light. The fluorescent material layer is disposed on the light emitting element. The fluorescent material layer is excited by the first light to emit second light being longer in wavelength than the first light. The reflective film is disposed on the fluorescent material layer to reflect part of the first light and transmit the second light. The light-transmissive member is disposed on the reflective film. The absorbing layer is disposed on the light-transmissive member to absorb part of the first light. The light emitting element is identical in area to or smaller in area than the fluorescent material layer in a plan view.
