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.
