Abstract

A display device according to an exemplary embodiment includes a display panel including a display area and a bending region. The display panel in the bending region includes a plurality of connection wires, a pattern including a plurality of electrodes, and a protection layer positioned between the plurality of connection wires and the pattern.

Claims (49)

1. A display device comprising:

a display panel including a display area for displaying an image and a non-display area, the non-display area including a bending region,

wherein the display panel in the bending region includes:

a plurality of connection wires,

a pattern including a plurality of electrodes, and

a protection layer positioned between the plurality of connection wires and the pattern,

wherein each electrode is insulated and is not configured to transmit electric signals, and

wherein the pattern is electrically isolated from the plurality of connection wires.

2. The display device of claim 1 , wherein,

the plurality of electrodes are arranged over at least about 50% of the bending region.

3. The display device of claim 2 , wherein,

each electrode is quadrangular or circular.

4. The display device of claim 2 , wherein,

the display panel further includes a substrate, and

the plurality of connection wires are positioned to cross the bending region on the substrate and configured to transmit signals from outside the display panel.

5. The display device of claim 4 , wherein,

the protection layer is positioned on the plurality of connection wires, and the pattern is positioned on the protection layer.

6. The display device of claim 5 , wherein,

the display panel further includes a pixel electrode positioned in the display area, and

the pattern is made of a same material as the pixel electrode.

7. The display device of claim 4 , wherein,

the protection layer is positioned between the substrate and the plurality of connection wires, and the pattern is positioned between the substrate and the protection layer.

8. The display device of claim 7 , wherein,

the display panel further includes a gate electrode positioned in the display area, and

the pattern is made of a same material as the gate electrode.

9. The display device of claim 1 , wherein,

the display panel further includes a first alignment mark and a second alignment mark respectively positioned at both sides of the bending region, and

the pattern is positioned between the first alignment mark and the second alignment mark.

10. The display device of claim 1 , wherein,

the pattern further includes a plurality of dummy electrodes adjacent to the bending region.

11. A display device comprising:

a display panel including a display area for displaying an image and a non-display area, the non-display area including a bending region; and

a protection film positioned on one surface of the display panel to not overlap the bending region,

wherein the display panel includes a pattern including a plurality of electrodes arranged in the bending region, wherein each electrode is insulated and is not configured to transmit electric signals,

the protection film includes a first portion and a second portion respectively positioned at both sides of the bending region, and

a portion of the pattern overlaps at least one of the first portion and the second portion, wherein the pattern includes a plurality of sub-patterns, and

each sub-pattern includes a plurality of electrodes of which a number is changed farther from the edge of the bending region, wherein the plurality of electrodes are separated from each other.

12. The display device of claim 11 , wherein,

the plurality of electrodes are positioned symmetrically with respect to one edge of the bending region.

13. The display device of claim 12 , wherein, each sub-pattern includes a plurality of electrodes of which a number increases farther from the edge of the bending region.

14. The display device of claim 12 , wherein, each electrode is quadrangular or circular.

15. The display device of claim 12 , wherein, each sub-pattern includes a plurality of electrodes having two or more kinds of shapes.

16. The display device of claim 11 , wherein, the display panel further includes a substrate and a plurality of connection wires crossing the bending region on the substrate, and the pattern is positioned at a same layer as the plurality of connection wires.

17. The display device of claim 16 , wherein,

in the bending region, the display panel further includes a first protection layer positioned between the substrate and the plurality of connection wires and a second protection layer positioned on the plurality of connection wires, and

the pattern is positioned between the first protection layer and the second protection layer.

18. The display device of claim 16 , wherein,

the display panel further includes a source electrode and a drain electrode positioned in the display area, and

the pattern is made of a same material as the source electrode and the drain electrode.
