Method of forming an electrode, display apparatus and method of manufacturing the same

摘要

A display apparatus includes a substrate, a metal electrode and a transparent electrode. The metal electrode is disposed over the substrate. The metal pattern includes metal having a work function of at least about 4.0 eV and optical reflectivity of at least about 90%. The transparent electrode is disposed over the substrate such that the transparent electrode overlays the metal pattern. The metal electrode may include gold or silver. The metal electrode may be formed through an ink-jet printing method or a screen printing method. By using a high-reflectivity metal, luminance is enhanced.
