Abstract: An organic light-emitting diode (OLED) display device and a method of fabricating the same can reduce resistance of a cathode by forming an auxiliary electrode. Also, such OLED display device and method can prevent damage on a pad electrode due to an etchant during patterning of an anode by applying a protective structure to the pad electrode of a pad area and by including the pad electrode exposed from a plurality of pad electrode layers.

Abstract: Provided are an organic light emitting display device and a manufacturing method thereof. In the organic light emitting display device, after an auxiliary electrode having a multilayer structure including different kinds of metals different in etching speed is formed, a void is formed within the auxiliary electrode upon formation of an anode. The resulting structure is created by a simplified process, with contact reliability between a cathode and the auxiliary electrode being enhanced, while resistance of the cathode is reduced.
