Abstract: A display device includes a display area and a non-display area disposed around the display area and including a pad area. The display device includes a resistance checker disposed in the non-display area, resistance test pads disposed in the pad area, resistance test lines connecting the resistance checker with the resistance test pad, and crack test lines disposed on the outer side of the resistance checker. The resistance test lines intersect the crack test lines in a plan view.
