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.
