Abstract

A display device including: a substrate including a display area, a peripheral area, and a pad area; a first main voltage line in the peripheral area, and a first connector extending from the first main voltage line to the pad area; and a second main voltage line in the peripheral area, and a second connector extending from the second main voltage line to the pad area, wherein each of the first connector and the second connector includes a first and second layer overlapping each other with a first insulating layer therebetween, the first insulating layer is in the display area and the peripheral area, the peripheral area includes an open area exposing the first and second connector and surrounding the display area, and the first insulating layer includes slits between the first and second connector and extending from an end of the first insulating layer toward the display area.

First claim

What is claimed is:

1. A display device comprising:
a substrate comprising a display area, a peripheral area outside the display area, and a pad area in the peripheral area;
a first main voltage line arranged in the peripheral area of the substrate and between an edge of the display area and the pad area, and a first connector extending from the first main voltage line to the pad area; and
a second main voltage line arranged in the peripheral area of the substrate and corresponding to another edge of the display area, and a second connector extending from the second main voltage line to the pad area,
wherein each of the first connector and the second connector comprises a first layer and a second layer overlapping each other with a first insulating layer therebetween, wherein the first insulating layer is arranged in the display area and the peripheral area of the substrate,
the peripheral area comprises an open area exposing the first connector and the second connector and surrounding the display area, and
the first insulating layer comprises a plurality of slits arranged between the first connector and the second connector and extending from an end of the first insulating layer toward the display area.

2. The display device of claim 1 , further comprising a second insulating layer on the second layer within the open area.

3. The display device of claim 2 , wherein the second insulating layer further comprises a height difference reducer at a boundary with the open area between the first connector and the second connector, and
a thickness of the height difference reducer is less than a thickness of the second insulating layer.

4. The display device of claim 3 , wherein two opposite distal ends of the height difference reducer overlap the first connector and the second connector, respectively.

5. The display device of claim 2 , wherein the second insulating layer comprises a plurality of concave portions respectively overlapping with the plurality of slits.

6. The display device of claim 1 , wherein, in the open area, the first connector and the second connector each comprise the second layer and do not comprise the first layer.

7. The display device of claim 6 , wherein, in the open area, a side of the first connector and a side of the second connector comprise an embossed structure.

8. The display device of claim 1 , wherein, in an area in which the second layer overlaps the first layer, the second layer comprises a plurality of holes exposing the first insulating layer.

9. The display device of claim 8 , wherein the plurality of holes constitute a plurality of rows and holes in two rows adjacent to each other, among the plurality of rows, are arranged to cross each other in a longitudinal direction.

10. The display device of claim 9 , wherein the first insulating layer comprises a plurality of contact holes via which the first layer is connected to the second layer and the plurality of contact holes are arranged between the plurality of holes, respectively.

11. A display device comprising:
a substrate comprising a display area, a peripheral area outside the display area, and a pad area in the peripheral area;
a first main voltage line arranged in the peripheral area of the substrate and between an edge of the display area and the pad area, and a first connector extending from the first main voltage line to the pad area; and
a second main voltage line arranged in the peripheral area of the substrate and corresponding to another edge of the display area, and a second connector extending from the second main voltage line to the pad area,
wherein each of the first connector and the second connector comprises a structure in which a first layer and a second layer are stacked,
a first insulating layer is arranged between the first layer and the second layer, and a second insulating layer is arranged on the second layer,
the peripheral area comprises an open area exposing parts of the first connector and the second connector and surrounding the display area, and
the second insulating layer comprises a height difference reducer at a boundary of the open area between the first connector and the second connector, wherein the height difference reducer has a thickness less than a thickness of the second insulating layer.

12. The display device of claim 11 , wherein two opposite distal ends of the height difference reducer overlap the first connector and the second connector, respectively.

13. The display device of claim 11 , wherein, in the open area, the first connector and the second connector each comprise the second layer and do not comprise the first layer.

14. The display device of claim 13 , wherein, in the open area, a side of the first connector and a side of the second connector comprise an embossed structure.

15. The display device of claim 13 , wherein, in an area in which the second layer overlaps the first layer, the second layer comprises a plurality of holes exposing the first insulating layer.

16. The display device of claim 15 , wherein the plurality of holes constitute a plurality of rows and holes in two rows adjacent to each other, among the plurality of rows, are arranged to cross each other in a longitudinal direction.

17. The display device of claim 15 , wherein the first insulating layer comprises a plurality of contact holes via which the first layer is connected to the second layer and the plurality of contact holes are arranged between the plurality of holes, respectively.

18. The display device of claim 11 , wherein the first insulating layer comprises a plurality of slits arranged between the first connector and the second connector and extending from an end of the first insulating layer toward the display area.

19. The display device of claim 18 , wherein the second insulating layer comprises a plurality of concave portions respectively overlapping with the plurality of slits.

20. The display device of claim 11 , wherein, in the open area, at least one dam is arranged and surrounds the display area.
