LIGHT EMITTING DIODE WITH HIGH EFFICIENCY

摘要

A light emitting diode includes: a light emitting structure including a second semiconductor layer and a first semiconductor layer; a first electrode electrically connected to the first semiconductor layer; a current blocking layer disposed on a lower surface of the light emitting structure; and a second electrode electrically connected to the second semiconductor layer, wherein the second electrode includes a first reflective metal layer adjoining the second semiconductor layer and a second reflective metal layer covering a lower surface of the current blocking layer and a lower surface of the first reflective metal layer while adjoining a portion of the second semiconductor layer, and wherein contact resistance between the second reflective metal layer and the second semiconductor layer is higher than contact resistance between the first reflective metal layer and the second semiconductor layer.
