A display device for preventing a damage of an electrode contact portion is disclosed. The display device includes a display area, on which an organic light emitting diode including a first electrode, an organic layer, and a second electrode is positioned, and a non-display area positioned outside the display area. The non-display area includes an electrode contact portion in which the second electrode and a low potential voltage line are connected to each other through at least one connection pattern. The electrode contact portion includes a passivation layer including a plurality of passivation holes exposing the at least one connection pattern, and an overcoat layer including an overcoat hole exposing the passivation layer.
