Abstract:
1. A light-emitting device comprising: a substrate; a light-emitting layer formed on the substrate; a transparent electrode layer formed on the light-emitting layer, the transparent electrode layer having a curved surface, wherein the curved surface is an inverted-opal structure having a crest-trough distance of approximately half or lower than a diameter of spheres forming an opal structure corresponding to the inverted-opal structure across the transparent electrode layer; and a reflective layer formed on and along the curved surface of the transparent electrode layer such that the curved surface of the transparent electrode layer is transferred so as to reflect the light generated from the light-emitting layer toward the light-emitting layer; wherein the curved surface of the transparent electrode layer is fabricated by the steps of: forming the transparent electrode layer on the light-emitting layer; forming photoresists on the transparent electrode layer; and performing a wet etching process on the transparent electrode layer to remove the photoresists to thereby form the curved surface on the transparent electrode layer.
