Description of the Invention: [Technical Field] The present invention relates to a light-emitting element and a method of fabricating the same, and more particularly to an organic electroluminescent element (〇rganic Electroluminescence Device, OEL) and its making method. [Prior Art] The organic electroluminescent element has characteristics of self-luminous, wide viewing angle, high response speed, low driving voltage, full color, etc., and has been put into practical use in an organic electroluminescence display. In general, an organic electroluminescent device comprises an anode, a cathode, and an organic light-emitting layer positioned between the two electrodes. When an electric current is passed between the anode and the cathode to cause electrons and holes to be combined in the organic light-emitting layer to generate an exciton, the organic light-emitting layer can be made to emit light of different colors according to the characteristics of the material. In general, § 'in order to improve the light utilization efficiency of the organic electroluminescent element', another light enhancing layer is usually provided. FIG. 1 is a schematic view of a conventional organic electroluminescent device. Referring to Fig. 1 ', the organic electroluminescent device 100 includes a glass substrate 110, an anode 120, an organic light-emitting layer 130, a cathode 140, a cap plate 150, and a light-increasing layer 160. In particular, the light ray 132 emitted from the organic light-emitting layer 130 can be enhanced by the light-increasing layer 160, thereby improving light utilization efficiency. However, in the manufacturing process of the organic electroluminescent element 1 shown in FIG. 1, since the light-increasing layer 160 is adhered to the cap plate 150, an air gap is often caused between the cap plate 150 and the brightness enhancement layer 160. 17〇. Therefore, 5 200822357TW 19660_/η part of the light 132 will be unnecessarily scattered due to the influence of the air gap 170, so the brightness enhancement effect of the brightness enhancement layer 160 will be lowered. In order to solve this problem, most of the conventional techniques use a refractive index matching glue (not shown) to fill the air gap 170, or a microlens array to improve the light utilization efficiency. .rate. 2 is a schematic view of another conventional organic electroluminescent device. Referring to Fig. 2, the organic electroluminescent device 200 includes a glass substrate 210, a germanium anode 220, an organic light-emitting layer 230, a cathode 240, and a cap plate 250. It is to be noted that in the method of fabricating the organic electroluminescent device 200, the microlens array 212 is first formed on the glass substrate 210 by reactive ion etching (RIE). Next, members such as the anode 220, the organic light-emitting layer 230, the cathode 240, and the cap plate 250 are formed on the glass substrate 210. As described above, since the microlens array 212 is provided on the light exiting path, the light use efficiency of the organic electroluminescent element 200 can be improved. However, U is that the above-described process for fabricating the microlens array 212 on the glass substrate 210 by the reactive ion etching method is complicated, and therefore, it is disadvantageous for mass production of the organic electroluminescent element 200, and is also disadvantageous for reducing the manufacturing cost.
