Abstract:
A touch panel includes a first transparent substrate and a second transparent substrate which are bonded by a frame-shaped seal member. One of a surface of the first transparent substrate and a surface of the second transparent substrate is a protrusion formation surface, and the other is a protrusion facing surface. On the protrusion formation surface, protrusions and a first resistive film are formed. The first resistive film includes first contact regions covering tops of the protrusions. On the protrusion facing surface, a second resistive film that includes second contact regions facing the first contact regions is formed. The protrusion formation surface or the protrusion facing surface includes a void region where the resistive film is not formed. Insulating spacers regulate a given distance between the first contact regions and the second contact regions. A space between the first and second transparent substrates contains an insulating liquid.
