Method of fabricating display device

1. A method of fabricating a display device comprising:

providing a substrate in which a display region and a pad region formed around the display region are defined;

forming a conductive layer on the substrate;

forming a mask pattern by rolling a roller on the conductive layer; and

patterning the conductive layer using the mask pattern to form a line in the display region and a pad in the pad region,

wherein the pad is formed of a pattern having a second width corresponding to a first width of the line,

wherein the forming of the pad and the line comprises forming a gate line extending in a first direction, a gate pad connected to the gate line, and a gate test pad connected to the gate pad, and

wherein the gate test pad is extended from the gate pad and the gate pad and the gate test pad are formed as a single body.

2. The method claimed as claim 1 , wherein the pad includes a mesh pattern formed of a pattern having the second width.

3. The method claimed as claim 1 , wherein the pad is connected to the line.

4. The method claimed as claim 1 , wherein, in the forming of the pad and the line, an align key formed of a pattern having the second width is formed.

5. The method claimed as claim 1 , wherein the width of the pad is 0.5 mm to 2 mm and the first width of line is 20 μm to 300 μm.

6. The method claimed as claim 1 , wherein the forming of the pad and the line comprises forming a gate line extending in a first direction, a gate pad connected to the gate line, and a gate test pad connected to the gate pad.

7. The method claimed as claim 1 , further comprising:

forming an insulation film covering the pad; and

forming a contact hole that partially exposes the pad, by partially removing the insulation film,

wherein the contact hole has the shape extending in a direction in which the roller rolls.

8. The method claimed as claim 4 , wherein the align key has the shape of an island.
