Abstract
An organic light-emitting display device having a thin film transistor including an active layer, a gate electrode, a lower gate electrode, an upper gate electrode, an insulating layer covering the gate electrode, source and drain electrodes that are formed on the insulating layer and contact the active layer. An organic light-emitting diode is electrically connected to the thin film transistor and includes a pixel electrode formed at the same layer level as the lower gate electrode, an intermediate layer including an emission layer, and a counter electrode. A lower pad electrode is formed at the same layer level as the lower gate electrode and an upper pad electrode is formed at the same layer level as the upper gate electrode.
