Abstract:
A light-emitting device includes a light-emitting structure with a side surface, and a reflective layer covering the side surface. The light-emitting structure has a first light-emitting angle and a second light-emitting angle. The difference between the first light-emitting angle and the second light-emitting angle is larger than 15°.
