A lateral current blocking light emitting diode (LED) and a method of making the same are disclosed. The present invention features in that a trench is formed between the two electrodes via the technique of such as etching, wherein the depth of the trench reaches to at least the active layer, thereby blocking the lateral current between the two electrodes. With the use of the present invention, the possibility of the current passing through the active layer can be increased, thereby improving the brightness of the LED; and the chance of the photons emitted from the lateral of the trench can be raised wherein the photons are generated from the active layer, thereby increasing the output efficiency of the photons generated from the active layer.
