1. A touch screen comprising:

  • a substrate; and

    a plurality of row direction wirings and a plurality of column direction wirings which are disposed on said substrate to intersect through an insulating film in a stereoscopic view,wherein, throughout an intersection portion of each of said row direction wirings and each of said column direction wirings, the wiring widths of each of said row direction wirings and each of said column direction wirings are wider than a wiring width of each respective row direction wiring or each respective column direction wiring in a portion other than said intersection portion in a plan view and consequently capacitance at said intersection portion is increased with respect to said portion other than said intersection portion, andan occurrence of dielectric breakdown of said insulating film due to a touch on said touch screen is suppressed by said increased capacitance.
