Abstract
A transparent conductive layer structure for an LED is provided. The LED includes a reflecting layer, an N-type electrode, an N-type semiconductor layer, a light emitting layer, a P-type semiconductor layer, a current block layer, a transparent conductive layer and a P-type electrode that are stacked on a substrate. The current block layer is disposed between and separates the P-type electrode and the P-type semiconductor layer. The transparent conductive layer is disposed between the P-type electrode and the current block layer, and connects to the P-type electrode and the P-type semiconductor layer. At a region corresponding to the P-type electrode, a plurality of holes are disposed at the transparent conductive layer to reduce an area of and hence an amount of light absorbed by the transparent conductive layer, thereby increasing light extraction efficiency of excited light from the light emitting layer and enhancing light emitting efficiency of the LED.
