Display device

A display device comprising:

• a substrate having an opening, a display area adjacent to the opening, and a non-display area between the opening and the display area;
• a plurality of display elements at the display area, the plurality of display elements each comprising a pixel electrode, an opposite electrode, and an intermediate layer between the pixel electrode and the opposite electrode;
• a thin-film encapsulation layer on the plurality of display elements, the thin-film encapsulation layer comprising at least one inorganic encapsulation layer and at least one organic encapsulation layer;
• and
• a metal stacked structure on the non-display area, the metal stacked structure comprising:
• a first sub-metal layer having a first hole;
• and
• a second sub-metal layer under the first sub-metal layer and having a second hole overlapping with the first hole,
• wherein an edge of the first sub-metal layer that defines the first hole comprises a tip that extends further toward a center of the first or second hole than an edge of the second sub-metal layer that defines the second hole,
• wherein the intermediate layer comprises at least one organic material layer, and
• wherein one or more of the opposite electrode and the at least one organic material layer is separated by the tip.
