Display device

A display device comprising:

• a substrate comprising a display area, on which a plurality of pixels is disposed, and a pad area positioned in a periphery of the display area;
• a first insulating layer disposed on the substrate;
• a first pad and a second pad electrode-which are disposed on the first insulating layer in the pad area and arranged in a first direction, each pad comprising a first pad electrode in contact with the first insulating layer and a second pad electrode positioned on the first pad electrode;
• a first peeling prevention structure disposed on the first insulating layer in the pad area to be spaced apart from the first pad in a second direction intersecting the first direction, wherein the first peeling prevention structure includes a first side surface facing the first pad and a second side surface opposite to the first side surface thereof;
• a second peeling prevention structure disposed on the first insulating layer in the pad area to be spaced apart from the second pad in the second direction, wherein second peeling prevention structure includes a first side surface facing the second pad and a second side surface opposite to the first side surface thereof;
• and
• a second insulating layer disposed on the first pad, the second pad, the first peeling prevention structure, and the second peeling prevention structure,
• wherein
• at least a part of the substrate positioned outside the second side surface of the first peeling prevention structure is exposed, and
• a portion of the substrate positioned outside the second side surface of the second peeling prevention structure is covered by the second insulating layer.
