description A method of fabricating method light-emitting diode according to an exemplary embodiment of the present invention includes forming a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer on a first substrate, forming a second substrate on the second conductivity-type semiconductor layer, separating the first substrate from the first conductivity-type semiconductor layer, forming a mask pattern including a plurality of openings on the first conductivity-type semiconductor layer exposed after separating the substrate, etching the first conductivity-type semiconductor layer having the mask pattern disposed thereon to form a plurality of recesses separated from each other, removing the mask pattern, and etching a surface of the first conductivity-type semiconductor layer to form a sub-micro texture.
