Claim 4:
5. A display device comprising:
a display area and a non-display area disposed around the display area and comprising a pad area,
a resistance checker disposed in the non-display area;
resistance test pads disposed in the pad area and arranged along a first direction;
resistance test lines connecting the resistance checker with the resistance test pads; and
