Abstract: A touch sensor includes a substrate, a touch input unit, a plurality of wires, and a pad unit. The touch input unit is disposed on the substrate and includes a plurality of sensing electrodes for sensing user touch. The pad unit includes a plurality of pads electrically connected to the sensing electrodes through the wires. The pads include a first pad. The first pad includes a first conductive film disposed on the substrate, an insulating film disposed on the first conductive film, and a second conductive film disposed on the insulating film. The insulating film includes a plurality of first-type holes and a plurality of second-type holes. Each first-type hole of the first-type holes is smaller than each second-type hole of the second-type holes.

Abstract: A touch sensing device includes a base layer, a touch electrode layer, a first reinforcing member, and a touch circuit board. The base layer includes a main area and a protruding area protruding from the main area in a first direction. The touch electrode layer is disposed on a surface of the base layer. The first reinforcing member is disposed on a surface of the protruding area. The touch circuit board is electrically connected to the touch electrode layer. The protruding area includes a bending area and a pad area. The bending area is bent downward. The pad area extends from the bending area in the first direction and overlaps the base layer in a second direction intersecting the first direction in a bent state of the bending area. The touch circuit board is attached to the pad area.
