Abstract
A light-emitting diode includes an epitaxial unit, a first electrode, and a second electrode. One of the first electrode and the second electrode includes a first reflective layer, a wire-bonding electrode layer, a second reflective layer wrapping a portion of the wire-bonding electrode layer, and a stress adjustment layer which wraps around the first reflective layer. The first reflective layer includes platinum, and the second reflective layer includes a material which has a Mohs hardness of not less than 6. The stress adjustment layer has a Mohs hardness of not less than 6, and the stress adjustment layer has a thickness that is 65% to 75% of a thickness of the first reflective layer.
