Patent ID: 8461591

Claim:
An organic light emitting display device comprising: a substrate having a display area and a non-display area; a thin film transistor in the display area; a wiring portion in the non-display area; an intermediate layer electrically connected to the thin film transistor and comprising an organic light emitting layer; and a counter electrode on the intermediate layer, wherein the thin film transistor comprises an active layer, a gate electrode insulated from the active layer, and source/drain electrodes that are insulated from the gate electrode and electrically connected to the active layer, wherein the source/drain electrodes comprise a first conductive layer, a second conductive layer, and a third conductive layer that are sequentially stacked, wherein the wiring portion comprises a same material as the first conductive layer and a different material from the second conductive layer and the third conductive layer, wherein one of the source/drain electrodes is longer than an other of the source/drain electrodes, to function as a pixel electrode, and wherein the one of the source/drain electrodes and the intermediate layer are electrically connected to each other.
