Light emitting diode with multiple transparent conductive layers and method for manufacturing the same

A light emitting diode, comprising:

• a first-type semiconductor layer;
• an active layer formed on the first-type semiconductor layer;
• a second-type semiconductor layer formed on the active layer;
• and
• a transparent, electrically conductive layer formed on the second-type semiconductor layer, the transparent, electrically conductive layer comprising a first transparent, electrically conductive layer on the second-type semiconductor layer and a second transparent, electrically conductive layer on the first transparent, electrically conductive layer;
• wherein the first transparent, electrically conductive layer and the second transparent, electrically conductive layer are both made of indium tin oxide, a concentration of oxygen in the first transparent, electrically conductive layer is lower than that in the second transparent, electrically conductive layer, and a thickness of the first transparent, electrically conductive layer is smaller than that of the second transparent, electrically conductive layer.
