1. A flexible touch sensor, comprising:
- a sensing electrode structure disposed on a flexible substrate and comprising;
a first insulating layer;
a first patterned conductive layer disposed on the first insulating layer, wherein;
the first insulating layer is disposed between the flexible substrate and the first patterned conductive layer, andthe first insulating layer directly contacts the flexible substrate;
a first wire layer disposed on the first insulating layer, wherein the first wire layer is electrically connected with the first patterned conductive layer;
a joint where the first wire layer directly contacts the first patterned conductive layer;
a second insulating layer disposed on the first patterned conductive layer, wherein the second insulating layer overlies a portion of the first patterned conductive layer but avoids the joint;
a second patterned conductive layer formed on the second insulating layer;
a second wire layer electrically connected with the second patterned conductive layer, wherein the second wire layer is disposed on the second insulating layer and on a same surface of the second insulating layer as the second patterned conductive layer; and
a protection layer disposed over the second patterned conductive layer and in contact with the first insulating layer, wherein;
the protection layer directly contacts the joint,the protection layer directly or indirectly contacts a to surface and a sidewall of the first wire layer, andthe protection layer directly contacts a to surface and a sidewall of the second insulating layer.

Abstract
A touch panel comprises a flexible touch sensor and a cover plate. The cover plate and the flexible touch sensor are attached to each other by an adhesive layer. The flexible touch sensor at least comprises a sensing electrode structure disposed on a flexible substrate. The sensing electrode structure comprises a first insulating layer and a first patterned conductive layer formed on the first insulating layer. The first insulating layer is disposed between the flexible substrate and the first patterned conductive layer and directly contacts the flexible substrate.
