Abstract
An organic light-emitting diode (OLED) display device and a method of fabricating the same can reduce resistance of a cathode by forming an auxiliary electrode. Also, such OLED display device and method can prevent damage on a pad electrode due to an etchant during patterning of an anode by applying a protective structure to the pad electrode of a pad area and by including the pad electrode exposed from a plurality of pad electrode layers.
