摘要:
A organic light emitting display device includes a thin film transistor (TFT) having a gate electrode, a source electrode and a drain electrode which are insulated from the gate electrode, and a semiconductor layer which is insulated from the gate electrode and which contacts each of the source electrode and the drain electrode; and a pixel electrode electrically connected to one of the source electrode and the drain electrode. The gate electrode is made up of a first conductive layer and a second conductive layer on the first conductive layer, and the pixel electrode is formed of the same material as the first conductive layer of the gate electrode on a same layer as the first conductive layer of the gate electrode.
