Abstract:
In a transparent electrode based on a metal material having reduced light reflectance, a light absorbing layer having black characteristic is formed on a lower surface, a partition wall, and/or an upper surface of a metal wire, and thus, light reflectance of transparent electrode is minimized. In a method of manufacturing a transparent electrode, the light absorbing layer can be selectively formed on the upper and lower surfaces and the partition wall of the metal wire having a fine line width by using self-aligning and a spontaneous pattern effect. A conductive wire is implemented by using an imprinting process using an elastic body-based stamp, and thus, conductive wires having a fine line width and an excellent aspect ratio can be formed, so that it is possible to improve electric conductivity and transmittance.
