Abstract
A light-emitting device includes a light-emitting structure with a side surface, and a reflective layer covering the side surface, and a light-transmitting body. The light-transmitting body encloses the light-emitting structure and has a first side surface, a second side surface, a third side surface and a fourth side surface. The reflective layer covers the first side surface and the third side surface without covering the second side surface and the fourth side surface. The light-emitting structure has a first light-emitting angle and a second light-emitting angle different from the first light-emitting angle.
