More Information
Summary:This disclosure discloses a light-emitting device. The light-emitting device includes a light-emitting stack having a first-type semiconductor layer, a second-type semiconductor layer, and an active layer formed between the first-type semiconductor layer and the second-type semiconductor layer; and a reflective structure formed on the first-type semiconductor layer and having a first interface and a second interface. A critical angle at the first interface for a light emitted from the light-emitting stack is larger than that at the second interface. The reflective structure electrically connects to the first-type semiconductor layer at the first interface, and an area of the first interface is more than an area of the second interface in a top view.
