Abstract
An organic light-emitting display including a substrate, at least one thin film transistor, a pixel electrode and at least one pad electrode. The substrate is provided with a display area and a pad area spaced apart from the display area. The thin film transistor is disposed on the display area of the substrate, and includes an active layer, a gate electrode and source/drain electrodes. The pixel electrode is adjacent to the thin film transistor, and is electrically connected to the thin film transistor. The pad electrode is disposed on the pad area of the substrate, is formed of the same layer as the gate electrode or the source/drain electrodes, and is coupled with an external module.
