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.
Claims21
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;
- resistance test lines connecting the resistance checker with the resistance test pads;
- a crack detector disposed in the non-display area and connected to crack test lines passing between the resistance checker and the resistance test pads,
- wherein the resistance test lines intersect the crack test lines in a plan view, and
- wherein an outermost side of the crack detector is disposed inside than an outermost side of the resistance checker in a first direction intersecting a second direction in which the display area and the pad area are arranged, and
- the outermost side of the crack detector and the outermost side of the resistance checker mainly extend in the second direction, and
- wherein an entirety of the resistance test lines from the resistance checker to the resistance test pads only extend in the second direction and do not overlap the display area in the first direction.

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
- crack test lines passing between the resistance checker and the resistance test pads,
- wherein the resistance test lines intersect the crack test lines in a plan view, wherein each of the crack test lines comprises:
- a first test line part connected to the crack detector,
- a second test line part connected to the first test line part, and
- a third test line part connected to the second test line part,
- wherein the first test line part is extended in the first direction,
- wherein the second test line part is extended in a second direction intersecting the first direction,
- wherein the third test line part surrounds a longer side of the display area,
- wherein the resistance checker is disposed on one side of the first test line part in the second direction so that the resistance checker is disposed closer to the display area than the first test line part is in the second direction, and
- wherein a width of the resistance checker in the first direction is less than a length of the first test line part in the first direction.
