Flexible touch panel and flexible display device

1. A flexible touch panel, comprising:

a flexible substrate bent in a first direction; and

a touch sensor unit disposed on the flexible substrate, the touch sensor unit comprising:

first sensing electrodes separated from each other;

a connection part connecting adjacent first sensing electrodes to each other;

second sensing electrodes separated from each other;

a bridge extending in a second direction intersecting the first direction; and

connecting adjacent second sensing electrodes to each other; and

an insulation pattern disposed between the connection part and the bridge,

wherein:

the bridge contacts an upper surface of each of the adjacent second sensing electrodes at positions spaced apart from ends of each of the adjacent second sensing electrodes such that the insulation pattern overlaps only end portions of the adjacent second sensing electrodes located under the bridge in a plan view; and

the bridge is located at a different layer from the second sensing electrodes.

2. The flexible touch panel of claim 1 , wherein the second direction is perpendicular to the first direction.

3. The flexible touch panel of claim 1 , wherein:

each of the first sensing electrodes is separated from each other along a third direction;

each of the second sensing electrodes is separated from each other along a fourth direction intersecting the third direction;

the insulating pattern covers the connection part; and

the bridge is disposed on the connection part.

4. The flexible touch panel of claim 3 , wherein the first sensing electrodes and the connection part are integrally formed.

5. The flexible touch panel of claim 4 , wherein the second sensing electrodes are disposed on the same layer as the first sensing electrodes.

6. The flexible touch panel of claim 3 , wherein the bridge comprises a metal.

7. The flexible touch panel of claim 6 , wherein the second sensing electrodes comprise a transparent conductive material.

8. The flexible touch panel of claim 3 , wherein:

the insulating pattern comprises a bent surface; and

the bridge is bent along the bent surface.

9. The flexible touch panel of claim 1 , wherein the bridge comprises at least two sub-bridges separated from each other.

10. The flexible touch panel of claim 3 , wherein the second direction and the fourth direction intersect each other at an angle in the range of 5° to 80° .

11. The flexible touch panel of claim 3 , wherein the third direction is parallel to the first direction.

12. The flexible touch panel of claim 1 , further comprising a window disposed on the touch sensor unit, the window being bent in the first direction.

13. The flexible touch panel of claim 1 , wherein the bridge comprises a material having a lower electrical resistance than the second sensing electrodes.

14. The flexible touch panel of claim 1 , wherein the bridge has a length in the second direction greater than a width in the first direction.
