Abstract: A touch sensor includes a substrate having at least one bending portion; and a sensing pattern on the substrate, the sensing pattern including a first pattern and a second pattern, the first pattern being arranged along a first direction parallel to a surface of the substrate, the second pattern being arranged along a second direction, the second direction being parallel to the surface of the substrate and crossing the first direction. The second pattern includes unit patterns isolated from each other, and a bridge electrode electrically connecting neighboring unit patterns of the unit patterns. The bridge electrode extends along the same direction as a bending direction of the bending portion.
