A method of making a LED includes following steps. A substrate with an epitaxial growth surface is provided. A carbon nanotube layer is placed on the epitaxial growth surface. A semiconductor epitaxial layer is grown on the epitaxial growth surface, and the semiconductor epitaxial layer includes an N-type semiconductor layer, an active layer, a P-type semiconductor layer. The semiconductor epitaxial layer is etched to expose part of the carbon nanotube layer. A first electrode is formed on a surface of the semiconductor epitaxial layer which is away from the substrate. A second electrode is formed to electrically connect with the part of the carbon nanotube layer which is exposed. |
