    摘要: An exemplary embodiment of the present invention discloses a light emitting diode including a substrate having a first edge and a second edge opposite to each other, a light emitting structure disposed on the substrate, the light emitting structure including a first semiconductor layer and a second semiconductor layer, a plurality of first electrode pads arranged on an upper surface of the first semiconductor layer, the first electrode pads arranged in a vicinity of the first edge, a plurality of second electrode pads arranged on the second semiconductor layer, the second electrode pads arranged in a vicinity of the second edge, a plurality of first extensions, each first extension extending from a first electrode pad, and a plurality of second extensions, each second extension extending from a second electrode pad. The first extensions include intrusion parts extending in a direction from the first edge to the second edge, wherein the intrusion parts are spaced apart from each other and not connecting with the second electrode pads. Further, the second extensions include intrusion parts extending in a direction from the second edge to the first edge, wherein the first extension intrusion parts each extend into a region between two of the second extension intrusion parts.
