Abstract

Provided is an organic light emitting display device in which a driving thin film transistor (TFT) includes an oxide semiconductor pattern. The driving thin film transistor includes a gate electrode disposed under an oxide semiconductor pattern, and a dummy electrode, a source electrode and a drain electrode over the oxide semiconductor pattern, and the dummy electrode is electrically connected to the source electrode to increase the S-factor of the driving TFT. In addition, the organic light emitting display device of the present disclosure includes a plurality of switching TFTs including an oxide semiconductor pattern, and the plurality of switching TFTs includes a plurality of switching thin film transistors having different distances between the oxide semiconductor pattern and the gate electrode so as to have different threshold voltages.
