Abstract: An organic light emitting display device and a method of manufacturing the same are provided that may reduce the resistance of a second electrode and may prevent corrosion and metal migration of a pad electrode without adding a separate mask process, or while reducing the number of mask processes. In the organic light emitting display device, an auxiliary line is connected to a second electrode through an auxiliary electrode, which is provided in the same layer as a first electrode, and a pad cover electrode is configured to cover an upper surface and a side surface of a pad connection electrode so as to prevent the pad connection electrode connected to a pad from being exposed outward.
