1. A display device comprising:
a substrate including a pad area;
a first conductive pattern disposed in the pad area on the substrate;
an insulating layer disposed on the first conductive pattern and overlapping the first conductive pattern;
second conductive patterns disposed on the insulating layer, spaced apart from each other, and each comprising a planar bottom surface directly contacting the first conductive pattern through a contact hole formed in the insulating layer, the planar bottom surface extending from a first end of the insulating layer directly contacting a first edge of the first conductive pattern to a second end of the insulating layer directly contacting a second edge of the first conductive pattern; and
a third conductive pattern disposed on the second conductive patterns and contacting the insulating layer.
