Light emitting device and method of fabricating the same

摘要

A light-emitting device according to an exemplary embodiment of the present invention includes a first conductivity-type semiconductor layer (130) disposed on a substrate (110); an active layer (140) disposed on the first conductivity-type semiconductor layer; a second conductivity-type semiconductor layer (150) disposed on the active layer; and an irregular convex-concave pattern (190) disposed on a surface of the first conductivity-type semiconductor layer. The irregular convex-concave pattern includes convex portions and concave portions, and the convex portions have irregular heights and the concave portions have irregular depths. The first conductivity-type semiconductor layer (130) including the irregular convex-concave pattern (190) is exposed from the active layer (140) and the second conductivity-type semiconductor layer (150).
