Abstract: Disclosed is an organic light emitting display device which includes an auxiliary line connected to a first power line and an auxiliary electrode connected to a second power line, thereby lowering a line resistance of each of the first and second power lines. The organic light emitting display device includes a substrate, a thin film transistor (TFT) disposed on the substrate, a first power line disposed in a first layer including the source electrode and the drain electrode of the TFT, a second power line disposed over the first layer, an auxiliary line disposed in a second layer including the second power line, an anode electrode disposed on the second power line and the auxiliary line and electrically connected to the drain electrode, an organic layer disposed on the anode electrode, and a cathode electrode covering the organic layer and electrically connected to the second power line.
