Abstract
A display panel may include a first display substrate. The first display substrate may include a base layer defining a display area and a non-display area that is adjacent to the display area, a gate line disposed on the base layer, a first insulating layer disposed on the base layer and covering the gate line, and a test line overlapping the non-display area and disposed on the first insulating layer, the test line being in electric contact with the gate line through a first contact hole defined in the first insulating layer.
Claims20
A display panel, comprising
- a first display substrate,
- wherein the first display substrate comprises:
- a base layer defining a display area and a non-display area that is adjacent to the display area;
- a gate line disposed on the base layer, wherein the gate line comprises a line portion extending in a specific direction and a pad portion disposed on the same layer as the line portion;
- the pad portion continuously and physically connected to the line portion in the same layer;
- a first insulating layer disposed on the base layer and covering the gate line;
- and
- a test line overlapping the non-display area and disposed above the first insulating layer, wherein the test line covers a first contact hole defined in the first insulating layer and electrically contacts the pad portion of the gate line through the first contact hole.
A method of fabricating of a display panel, comprising:
- forming a gate line on a first base layer, the gate line including a line portion that extends in a specific direction and a pad portion disposed on the same layer as the line portion;
- the pad portion is continuously and physically connected to the line portion in the same layer;
- forming a first insulating layer on the first base layer to cover the gate line;
- etching a portion of the first insulating layer to form a first contact hole exposing at least a portion of the pad portion of the gate line;
- forming a test line above the first insulating layer, the test line covering the first contact hole and electrically contacting the pad portion of the gate line through the first contact hole;
- and
- coupling a second base layer to the first base layer using an adhesive member.
A display panel, comprising:
- a base layer defining a display area and a non-display area that is adjacent to the display area;
- a signal line disposed on the base layer, the signal line comprising a connection line portion and a line portion, each of which is extended in a specific direction, and a pad portion that is disposed between the connection line portion and the line portion;
- an insulating layer disposed on the base layer and covering the signal line;
- and
- a test line overlapping the non-display area, being disposed on the insulating layer, and covering at least one contact hole defined in the insulating layer electrically contacting the pad portion of the signal line through the at least one contact hole,
- wherein the connection line portion, the line portion, and pad portion are disposed on the same layer as one another,
- wherein the test line comprises a test line portion which is extended in the specific direction and a test pad portion that is physically connected to the test line portion,
- wherein the test pad portion overlaps the pad portion in a plan view.
