Abstract: A display device includes a substrate having a display area and a non-display area, a pixel electrode, an organic emissive layer, a common electrode, a first inorganic encapsulation layer, an organic encapsulation layer, a second inorganic encapsulation layer, a dam, a bank disposed closer to a peripheral edge of the substrate than the dam, an inorganic encapsulation area, wherein the first inorganic encapsulation layer contacts the second inorganic encapsulation layer in the inorganic encapsulation area, and a first voltage supply line in a bank area where the bank is disposed, and in the inorganic encapsulation area. The first voltage supply line includes a plurality of anti-moisture patterns protruding from one side of the first subsidiary voltage supply line and having at least one of a length and a width in the inorganic encapsulation area respectively different from those of the plurality of anti-moisture patterns in the bank area.
