Abstract

A display device is disclosed. In one aspect, the display device includes a substrate and a plurality of scan lines formed over the substrate and separated from each other in a first direction. The scan lines extend in a second direction crossing the first direction. The display device also includes a stress compensation layer positioned between adjacent ones of the scan lines.

Claims (29)

1. A display device comprising:

a substrate;

a plurality of scan lines on the substrate and separated from each other in a first direction, wherein the scan lines extend in a second direction crossing the first direction;

a stress compensation layer positioned between adjacent ones of the scan lines; and

an insulating layer covering the stress compensation layer, wherein the stress compensation layer comprises a different material from that of the insulating layer.

2. The display device of claim 1 , wherein the stress compensation layer is configured to electrically float.

3. The display device of claim 1 , wherein the stress compensation layer overlaps at least one of the adjacent scan lines in the depth dimension of the display device.

4. The display device of claim 1 , wherein the stress compensation layer does not overlap the adjacent scan lines in the depth dimension of the display device.

5. The display device of claim 1 , wherein the stress compensation layer is positioned between the substrate and one of the adjacent scan lines.

6. The display device of claim 1 , further comprising another insulating layer that covers the scan lines, wherein the stress compensation layer is positioned on the other insulating layer.

7. The display device of claim 1 , wherein the stress compensation layer is positioned on the same layer as the adjacent scan lines.

8. The display device of claim 1 , wherein the stress compensation layer includes:

a first sublayer positioned over the substrate; and

a second sublayer positioned over the first sublayer.

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

a plurality of transistors electrically connected to at least one of the scan lines; and

a plurality of organic light-emitting diodes (OLEDs) electrically connected to the transistors.

10. The display device of claim 9 , wherein each of the transistors includes:

an active layer positioned over the substrate; and

a gate electrode positioned over the active layer.

11. The display device of claim 10 , wherein the stress compensation layer is positioned on the same layer as the active layer.

12. The display device of claim 10 , wherein the stress compensation layer is positioned on the same layer as the gate electrode.

13. The display device of claim 9 , further comprising a plurality of data lines crossing the scan lines and electrically connected to at least one of the transistors.

14. The display device of claim 13 , wherein the stress compensation layer crosses the data lines.

15. The display device of claim 1 , wherein the stress compensation layer extends in the second direction.

16. The display device of claim 1 , wherein the stress compensation layer has a line shape.

17. The display device of claim 1 , wherein the stress compensation layer has an island shape.

18. The display device of claim 1 , wherein the substrate is flexible.

19. The display device of claim 1 , wherein the stress compensation layer has a Young's modulus greater than that of the insulating layer.
