    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.
