A method of the present invention for making a LED includes providing a semiconductor layer of a first polarity, forming an active layer on the semiconductor layer, and forming a semiconductor layer of a second polarity on the active layer. At least one side of at least the active layer and a semiconductor layer of the second polarity is of irregular shape. This shape thereby reduces the probability of reflecting light emitted from the active layer, thus making light emitted from the active layer penetrate through the at least one side and be emitted outside the LED.
