    Abstract: An LED with a current diffusion structure comprises an N-type semiconductor layer, a light emitting layer, a P-type semiconductor layer, an N-type electrode, a P-type electrode and a current blocking layer. The N-type semiconductor layer, light emitting layer and P-type semiconductor layer form a sandwich structure. The N-type and P-type electrodes are respectively arranged on the N-type and P-type semiconductor layers. The current blocking layer has the pattern of the N-type electrode and is embedded inside the N-type semiconductor layer. Thereby not only current generated by the N-type electrode detours the current blocking layer and uniformly passes through the light emitting layer, but also prevents interface effect to increase impedance. Thus is promoted lighting efficiency of LED. Further, as main light-emitting regions of the light emitting layer are far from the N-type electrode, light shielded by the N-type electrode is reduced and illumination of LED is thus enhanced.
