Claim Text:
1. A light-emitting diode, comprising: a second conductivity-type semiconductor layer disposed on a support substrate; a first conductivity-type semiconductor layer disposed on the second conductivity-type semiconductor layer; an active layer disposed between the first conductivity-type semiconductor layer and the second conductivity-type semiconductor layer; a passivation layer disposed on the first conductivity-type semiconductor layer, the second conductivity-type semiconductor, and the active layer; an insulating pattern layer disposed on a first region of the support substrate; and an electrode pad disposed on the first conductivity-type semiconductor layer, wherein: the first conductivity-type semiconductor layer comprises a plurality of recesses spaced apart from each other and a sub-micro texture disposed on an uppermost surface of the first conductivity-type semiconductor layer opposite to the support substrate excluding the plurality of recesses; the passivation layer is disposed in the plurality of recesses and on the sub-micro texture of the first conductivity-type semiconductor layer; the electrode pad is disposed on a portion of the sub-micro texture and at least one of the plurality of recesses of the first conductivity-type semiconductor layer.
