Abstract:
A semiconductor light emitting device includes a substrate structure; a semiconductor layer disposed on the substrate structure, the semiconductor layer including a light emitting layer; and an electrode formed on a surface of the semiconductor layer, wherein a relatively coarse uneven portion and a relatively fine uneven portion are formed by a frost process on a surface of the semiconductor layer at a side of the electrode.
