Description of the Invention: [Technical Field] The present invention relates to a light-emitting diode and a method of fabricating the same, and more particularly to an edge-lighting light-emitting diode and a method of fabricating the same. [Prior Art] The light-emitting devices in the conventional backlight module are generally a Cold Cathode Fluorescent Lamp (CCFL) and a Light Emitting Diode (LED). Among them, a light-emitting diode system is a solid-state semiconductor light-emitting device which combines two kinds of carriers (negatively charged electrons and positively charged holes) separated in a dipole to generate light. Compared with cold cathode fluorescent lamps, light-emitting diodes have the advantages of high color saturation, no mercury, long life and adjustable color temperature through drive current. Please refer to FIG. 1 , which is a schematic diagram of a backlight module using a conventional light-emitting diode. The backlight module 10 includes a reflective cover 11 including a light source, a transparent plastic plate 13 including a reflective sheet 131, and an optical sheet 14 for diffusing light. The light source includes a plurality of light emitting diodes 12, and each of the light emitting diodes 12 includes a semiconductor light emitting element 121 including a light emitting region 1211 and a light guiding prism 122 disposed on the semiconductor light emitting element 121. The light guiding prism 122 includes a light incident surface 1221 having a cross section of the light emitting region 1211 and a "gate" shape, and a funnel shaped reflecting surface 1222 opposite to the light incident surface 1221 and a light guiding surface. A light exit surface 1223 connected to the side of the prism 122 and connected to the reflective surface 1222. The light emitted from the semiconductor light-emitting element 121 enters the light-guiding prism 122 from the light-incident surface 1221, and the reflective surface 1222 reflects part of the incident light to the light-emitting surface 1223.
