Flexible touch panel and flexible display device
A flexible touch panel includes a flexible substrate bent in a first direction, and a touch sensor unit disposed on the flexible substrate, the touch sensor unit including a bridge extending in a second direction intersecting the first direction.
1. A flexible touch panel, comprising:
a flexible substrate; and
a touch sensor unit disposed on the flexible substrate, the touch sensor unit comprising:
a first sensing electrode comprising first portions and second portions that are arranged alternately in a first direction;
second sensing electrodes separated from each other arranged in a second direction crossing the first direction; and
a bridge extending in a third direction crossing the first direction, the bridge overlapping the second portion of the first sensing electrode,
wherein:
the second sensing electrodes comprise a same material as the first sensing electrode and are disposed at a same layer as the first sensing electrode; and
the bridge comprises a material different from the second sensing electrodes and is disposed at a different layer from the second sensing electrodes.
2. The flexible touch panel of claim 1 , wherein an area of the first portion is different from an area of the second portion in a plan view.
3. The flexible touch panel of claim 2 , wherein the area of the second portion is smaller than the area of the first portion.
4. The flexible touch panel of claim 1 , wherein the third direction is not parallel to the second direction.
5. The flexible touch panel of claim 4 , wherein an angle between the third direction and the second direction is in a range of 5° to 80°.
6. The flexible touch panel of claim 4 , wherein the second direction is perpendicular to the first direction.
7. The flexible touch panel of claim 1 , wherein the bridge comprises at least two sub-bridges separated from each other.
8. The flexible touch panel of claim 1 , further comprising an insulator disposed between the second portion of the first sensing electrode and the bridge in a sectional view.
9. The flexible touch panel of claim 8 , wherein:
the insulator comprises a bent surface; and
the bridge is bent along the bent surface.
10. The flexible touch panel of claim 1 , wherein the bridge comprises a metal.
11. The flexible touch panel of claim 10 , wherein the second sensing electrodes comprise a transparent conductive material.
