Abstract

A display device includes a substrate including a display area to display an image and a non-display area provided on at least one side of the display area, a plurality of pixels disposed on the substrate and provided in an area corresponding to the display area, a first insulating layer having an opening in a first area of the non-display area, a second insulating layer provided in the first area, first lines provided on the substrate and connected to the plurality of pixels, and second lines provided on the first and second insulating layers, and connected to the first lines. An area in which the first lines overlap with the second lines is spaced apart from an edge of the second insulating layer when viewed in a plan view.

First claim

What is claimed is:

a plurality of pixels disposed on the substrate and provided in an area corresponding to the display area;
a first insulating layer having an opening in a first area of the non-display area;
a second insulating layer filling the opening of the first insulating layer, wherein the second insulating layer contacts the substrate in the opening of the first insulating layer;
first lines provided on the substrate and connected to the plurality of pixels; and
second tines provided on the first and second insulating layers, and connected to the first lines,
wherein an area in which the first lines overlap with the second lines is spaced apart from an edge of the second insulating layer when viewed in a plan view.

2. The display device of claim 1 , wherein
the first lines include first pads provided at an end of each first line,
the second lines include second pads provided at an end of each second line, and
the first pads and the second pads overlap with each other when viewed in a plan view.

3. The display device of claim 2 , wherein the first insulating layer includes at least one contact hole in an area in which the first pads overlap with the second pads, and the first pads and the second pads are connected to each other through the at least one contact hole.

4. The display device of claim 3 , wherein the second insulating layer has a hole to expose an upper surface of the first insulating layer in a position corresponding to the first and second pads when viewed in a plan view.

5. The display device of claim 4 , wherein the hole has a greater area than the first and second pads.

6. The display device of claim 4 , wherein the hole has a smaller area than the first and second pads.

7. The display device of claim 6 , wherein the hole is provided in a position corresponding to the at least one contact hole of the first insulating layer when viewed in a plan view.

8. The display device of claim 2 , further comprising an insulating interlayer provided below the first insulating layer and having an opening in the first area,
wherein the first lines include first sub-lines provided below the insulating interlayer and second sub-lines provided on the insulating interlayer.

9. The display device of claim 8 , wherein the first sub-lines and the second sub-lines are alternately arranged when viewed in a plan view.

10. The display device of claim 8 , wherein the second lines include third sub-lines provided on the first insulating layer and fourth sub-lines provided on a third insulating layer.

11. The display device of claim 10 , wherein the third sub-lines and the fourth sub-lines are alternately arranged when viewed in a plan view.

12. The display device of claim 11 , wherein the first sub-lines are connected to the third sub-lines, and the second sub-lines are connected to the fourth sub-lines.

13. The display device of claim 2 , wherein the second insulating layer covers the first area and a portion of a second area adjacent to the first area.

14. The display device of claim 13 , wherein the first area is spaced apart from the display area.

15. The display device of claim 14 , wherein the edge of the second insulating layer is provided between the display area and the first area.

16. The display device of claim 2 , wherein widths of the first and second pads are greater than widths of portions of the first and second lines where the first and second pads are not overlapped.

17. The display device of claim 2 , wherein widths of the first and second pads are substantially the same as widths of portions of the first and second lines where the first and second pads are not overlapped.

18. The display device of claim 2 , wherein a distance between the edge of the second insulating layer and the display area is greater than a distance between the first and second pads and the display area when viewed in a plan view.

19. The display device of claim 2 , wherein a distance between the edge of the second insulating layer and the display area is shorter than a distance between the first and second pads and the display area when viewed in a plan view.

20. The display device of claim 2 , wherein the second lines comprise third sub-lines provided on the first insulating layer and fourth sub-lines provided on a third insulating layer.

21. The display device of claim 20 , wherein the third sub-lines and the fourth sub-lines are alternately arranged when viewed in a plan view.

22. The display device of claim 1 , further comprising a third insulating layer provided on the first and second insulating layers.

23. The display device of claim 22 , wherein the third insulating layer includes a second opening along an edge of the display area.

24. The display device of claim 22 , wherein each pixel comprises;
an active pattern provided on the substrate;
a gate insulating layer provided on the active pattern;
a gate electrode provided between the gate insulating layer and the first insulating layer;
a source electrode and a drain electrode provided on the first insulating layer;
a first electrode provided on the third insulating layer and connected to the drain electrode;
an organic layer provided on the first electrode; and
a second electrode provided on the organic layer.

25. The display device of claim 24 , wherein at least a portion of the first lines is provided on the same layer and with substantially the same material as the gate electrode.

26. The display device of claim 24 , wherein at least a portion of the second lines is provided on the same layer and with substantially the same material as the source electrode and the drain electrode.

27. The display device of claim 1 , wherein the first insulating layer comprises an inorganic material.

28. The display device of claim 1 , wherein the second insulating layer comprises an organic material.

29. The display device of claim 1 , wherein the first area extends in a first direction, and the substrate is bent along a folding line extending in the first direction.

30. The display device of claim 29 , wherein an area of the display device other than the first area is flat.
