Abstract: A touch sensor includes a substrate and first and second touch sensor electrode layers. The first touch sensor electrode layer is disposed on a first surface of the substrate, and includes a first pad formed on an opposing surface to a surface in contact with the substrate. The second touch sensor electrode layer is disposed on a second surface of the substrate, exposes at least a portion of the surface in contact with the substrate to an outside of the substrate, and includes a second pad formed on the portion exposed to the outside of the surface in contact with the substrate. The first pad and the second pad do not overlap in a stacking direction.
