Abstract:
1. A light emitting diode (LED) chip comprising: a semiconductor stack comprising a first conductivity-type semiconductor layer, a second conductivity-type semiconductor layer, and an active layer interposed between the first conductivity-type semiconductor layer and the second conductivity-type semiconductor layer; a first electrode pad disposed on the second conductivity-type semiconductor layer; a first electrode extension extending from the first electrode pad, the first electrode extension connected to the first conductivity-type semiconductor layer; a second electrode pad electrically connected to the second conductivity-type semiconductor layer; a first insulation layer interposed between the first electrode pad and the second conductivity-type semiconductor layer; a second electrode extension extending from the second electrode pad; a transparent conductive layer disposed on the second conductivity-type semiconductor layer; and a current blocking layer interposed between the transparent conductive layer and the second conductivity-type semiconductor layer, the current blocking layer extending along the second electrode extension, wherein the second electrode pad and the second electrode extension are electrically connected to the second conductivity-type semiconductor layer by the transparent conductive layer.
