Light-emitting device |
| abstract |
A light-emitting device is provided. The light-emitting device comprises The light-emitting device comprises a light-emitting stack comprising a first semiconductor layer, a second semiconductor layer and an active layer between the first semiconductor layer and the second semiconductor layer; and a third semiconductor layer on the light-emitting stack and comprising a first sub-layer, a second sub-layer and a roughened surface, wherein the first sub-layer has the same composition as that of the second sub-layer, and the second sub-layer is farther from the light-emitting stack than the first sub-layer; wherein the first sub-layer and the second sub-layer each comprises a Group III element and a Group V element, and an atomic ratio of the Group III element to the Group V element of the first sub-layer is less than an atomic ratio of the Group III element to the Group V element of the second sub-layer. |
