Abstract

A display device is disclosed. In one aspect, the display device includes a first wire disposed in the inactive area of the substrate, a first pad overlapping the first wire in the depth dimension of the display device, and a first connecting layer configured to electrically connect the first wire to the first pad. The display device also includes a second wire located on a different layer from the first wire, a second pad overlapping the second wire in the depth dimension of the display device, and a second connecting layer configured to electrically connect the second wire to the second pad.

Claims (42)

1. A display device, comprising:

a substrate comprising an active area including a plurality of pixels and an inactive area adjacent to the active area;

a first wire disposed in the inactive area of the substrate;

a first pad overlapping the first wire in the depth dimension of the display device;

a first connecting layer configured to electrically connect the first wire to the first pad;

a second wire located on a different layer from the first wire, wherein the second wire is located adjacent to the first wire;

a second pad overlapping the second wire in the depth dimension of the display device; and

a second connecting layer configured to electrically connect the second wire to the second pad.

2. The display device of claim 1 , wherein the first and second pads are located on different layers.

3. The display device of claim 1 , wherein the first and second connecting layers are located on the same layer.

4. The display device of claim 1 , wherein the first wire and the second pad are located on the same layer, and wherein the second wire and the first pad are located on the same layer.

5. The display device of claim 1 , wherein the first connecting layer is located over the first wire and the first pad, and wherein the second connecting layer is located over the second wire and the second pad.

6. The display device of claim 1 , wherein the first connecting layer contacts the first wire and the first pad, and wherein the second connecting layer contacts the second wire and the second pad.

7. The display device of claim 1 , further comprising:

a first insulating layer interposed between the first wire and the first pad, wherein the first insulating layer has a first hole; and

a second insulating layer interposed between the first pad and the first connecting layer, wherein the second insulating layer has a second hole, and

wherein the first and second holes overlap each other in the depth dimension of the display device.

8. The display device of claim 7 , wherein the first connecting layer contacts the first wire via the first hole and contacts the first pad via the second hole.

9. The display device of claim 7 , wherein the first pad has a first through hole overlapping the first and second holes in the depth dimension of the display device.

10. The display device of claim 9 , wherein the second hole is larger than the first through hole.

11. The display device of claim 1 , further comprising:

a first insulating layer interposed between the second pad and the second wire, wherein the first insulating layer has a third hole; and

a second insulating layer interposed between the second wire and the second connecting layer, wherein the second insulating layer has a fourth hole, and

wherein the third and fourth holes overlap each other in the depth dimension of the display device.

12. The display device of claim 11 , wherein the second wire has a second through hole overlapping the third and fourth holes in the depth dimension of the display device.

13. The display device of claim 12 , wherein the fourth hole is larger than the second through hole.

14. The display device of claim 1 , further comprising:

a thin film transistor located on the active area and comprising an active layer, a gate electrode, a source electrode, and a drain electrode; and

a storage capacitor located on the active area and comprising a first electrode and a second electrode disposed on the first electrode.

15. The display device of claim 14 , wherein the first wire and the second pad are located on the same layer as the gate electrode and the first electrode.

16. The display device of claim 14 , wherein the second wire and the first pad are located on the same layer as the second electrode.

17. The display device of claim 1 , wherein the first and second wires are electrically connected to signal lines passing through the active area.

18. The display device of claim 1 , wherein the first pad comprises a plurality of first sub-pads, wherein the second pad comprises a plurality of second sub-pads, and wherein the first sub-pads and the second sub-pads are alternately arranged in a first direction.

19. The display device of claim 1 , wherein the first wire includes a plurality of first sub-wires, wherein the second wire includes a plurality of second sub-wires, and wherein the first sub-wires and the second sub-wires are alternately arranged.

20. A display device, comprising:

a substrate comprising a display area including a plurality of pixels and a non-display area adjacent to the display area;

first and second wires disposed in the non-display area and located on different layers formed over the substrate;

a first pad overlapping the first wire in the depth dimension of the display device;

a second pad overlapping the second wire in the depth dimension of the display device,

a first connecting layer configured to electrically connect the first wire to the first pad; and

a second connecting layer configured to electrically connect the second wire to the second pad,

wherein the first and second wires are alternately arranged in parallel, and wherein the first and second pads are alternately arranged at corresponding ends of the first and second wires.
