Claim Text:
1. A light emitting diode comprising: a light emitting structure including a first-conductivity-type semiconductor layer, a second-conductivity-type semiconductor layer, and an active layer disposed between the first-conductivity-type semiconductor layer and the second-conductivity-type semiconductor layer; an electrode on the second conductivity-type semiconductor layer of the light emitting structure; and a mask layer disposed in the first-conductivity-type semiconductor layer; wherein the first-conductivity-type semiconductor layer includes at least one recess portion, wherein the light emitting structure is mesa-etched from the second-conductivity-type semiconductor layer to a part of the first-conductivity-type semiconductor layer, and wherein the mask layer is disposed in an upper part of the first-conductivity-type semiconductor layer as compared to a surface of the first-conductivity-type semiconductor layer exposed by the mesa-etching, wherein the mask layer includes a masking region and a window region that is distinguished from the masking region, and the recess portion is to correspond to the window region, and the electrode is to correspond to the window region.
