摘要:
A light-emitting device includes: a substrate; a first light emitter and a second light emitter which are disposed on the substrate; and a reflector which is disposed on the substrate and reflects light emitted by the first light emitter. The first light emitter, the reflector, and the second light emitter are aligned in stated order in a direction from a center toward a periphery of the substrate in a plan view. The first light emitter, the reflector, and the second light emitter decrease in height in stated order, the height being measured from the substrate.
