1. A display device comprising;
a substrate including a display area and a non-display area; and
a plurality of pads disposed in the non-display area,
wherein each of the pads includes a first electrode layer, a second electrode layer, a third electrode layer, a fourth electrode layer, and a fifth electrode layer which are sequentially disposed on the substrate,
a first insulating layer and a second insulating layer which clad an edge of the fourth electrode layer and are disposed between the fourth electrode layer and the fifth electrode layer, and
the second electrode layer is in contact with the first electrode layer by a contact hole penetrating through at least one insulating layer.
 
17. A display device comprising:
