LIGHT EMITTING DEVICE |
| 摘要 |
This disclosure discloses a light-emitting device. The light-emitting device comprise a light-emitting stack having a first-type semiconductor layer, a second-type semiconductor layer, and an active formed between the first-type semiconductor layer and the second-type semiconductor layer and emitting a light; and a reflective structure formed on the first-type semiconductor layer and having a first interface and a second interface; wherein the critical angle of the light at the first interface is larger than that at the second interface; and wherein the reflective structure ohmically contacts the first-type semiconductor layer at the first interface. |
