    Abstract: Discussed are an organic light emitting display device and a method of manufacturing the same. The organic light emitting display device according to an embodiment includes a substrate including an active area and a pad area, a thin film transistor (TFT) in the active area of the substrate, an anode electrode on the TFT, an organic emission layer on the anode electrode, a cathode electrode on the organic emission layer, an auxiliary electrode connected to the cathode electrode and disposed on the same layer as the anode electrode, a signal pad in the pad area of the substrate, and a pad electrode connected to the signal pad to cover a top of the signal pad for preventing the top of the signal pad from being corroded. The TFT includes a gate electrode. The signal pad is disposed on the same layer as the gate electrode.

    Abstract: Discussed is an organic light emitting display device in which an auxiliary electrode is disposed on an overcoating layer, and thus, an aperture ratio is enhanced. The organic light emitting display device can include a first overcoating layer disposed on a driving transistor and a supply electrode, a connection electrode disposed on the first overcoating layer and connected to the supply electrode through the second contact hole, a first electrode disposed on the first overcoating layer and connected to the driving transistor through the first contact hole, a second overcoating layer disposed on the first overcoating layer, and an auxiliary electrode disposed on the second overcoating layer and connected to the connection electrode. The first overcoating layer may include a first contact hole and a second contact hole. The second overcoating layer may cover the first and second contact holes and may not cover a portion of the first electrode.

    Abstract: An organic light emitting display device comprises a partition wall formed on a bank that covers a portion of an auxiliary electrode. The organic light emitting display device includes a first electrode, an auxiliary electrode, a first bank, and a partition wall. The first electrode may be connected to a driving transistor, and the auxiliary electrode may be disposed on the same layer as the first electrode. The first bank may cover a portion of the first electrode and a portion of the auxiliary electrode. A portion of a bottom surface of the partition wall may contact a top surface of the first bank, and the other portion except the portion of the bottom surface may be disposed on the auxiliary electrode.
