A light-emitting diode with a micro-lens layer, includes a die substrate, a second epitaxy layer deposited on the top surface of the die substrate, a first epitaxy layer deposited on a portion of the top surface of the second epitaxy layer, a second electrode formed on a portion of the top surface of the second epitaxy layer, a first electrode formed on a portion of the top surface of the first epitaxy layer, and a micro-lens layer mounted on a portion of the top surface of the first epitaxy layer. The micro-lens layer can change the projection angle and the projection path of the light beams radiated within the light-emitting diode in virtue of the diffusion effect caused by the micro-lens, and thereby improving the light-drawing efficiency and the luminance of the light-emitting diode.
