Abstract
A light emitting diode includes a light emitting structure, a transparent conductive layer and a transparent protecting layer formed in sequence. A plurality of holes are defined in the transparent protecting layer to expose the transparent conductive layer out of the transparent protecting layer. A plurality of micro-structures are formed on a top surface of the transparent conductive layer in the holes. The micro-structures refract light emitted from the light emitting structure and travelling through the transparent conductive layer.
