Abstract
An organic light emitting diode display includes a substrate including a display area and a pad area, a first thin film transistor disposed on the display area, an organic light emitting diode connected to the first thin film transistor, a pad electrode disposed on the pad area and a pad contact electrode disposed on an upper portion of the pad electrode and electrically connected to the pad electrode. The organic light emitting diode includes an anode, an organic emission layer, and a cathode. The anode includes a lower layer, an intermediate layer, and an upper layer. The pad contact electrode is formed of a material of the lower layer of the anode.
