Abstract:
1. A light emitting diode, comprising: a substrate comprising a first side edge and a second side edge; a light emitting structure arranged on the substrate, the light emitting structure comprising a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer; a transparent electrode layer arranged on the second conductivity-type semiconductor layer; a first electrode pad contacting an upper surface of the first conductivity-type semiconductor layer, the first electrode pad located near a center of the first side edge; two second electrode pads located near opposite distal ends of the second side edge, the two second electrode pads to supply electric current to the second conductivity-type semiconductor layer; a first pad extension extending from the first electrode pad; and a second pad extension extending from each of the two second electrode pads, the second pad extension contacting an upper surface of the transparent electrode layer, wherein the first pad extension comprises a first inserting portion extending from the first electrode pad towards the second side edge; and second inserting portions extending from a portion of the first inserting portion between a central region of the first inserting portion and the first electrode pad towards opposite sides of the first inserting portion along the first side edge.
