Patent ID: 8913025

Claim:
A touch screen comprising: a transparent substrate; a column direction wire bunch and a row direction wire bunch that are formed on said transparent substrate, said column direction wire bunch having a rectangular shape and including a plurality of detection column wires electrically connected commonly to each other, said row direction wire bunch having a rectangular shape and including a plurality of detection row wires electrically connected commonly to each other; and a dummy column direction wire bunch and a dummy row direction wire bunch, said dummy column direction wire bunch having a rectangular shape and including a plurality of dummy column wires electrically connected commonly to each other, said dummy row direction wire bunch having a rectangular shape and including a plurality of dummy row wires electrically connected commonly to each other, wherein said dummy column direction wire bunch is provided at the outer side of the outermost one of the detection column wires in a detection region including a plurality of said detection column wires and a plurality of said detection row wires, said dummy row direction wire bunch is provided at the outer side of the outermost one of the detection row wires in a detection region including a plurality of said detection column wires and a plurality of said detection row wires, in a plan view, a plurality of detection block regions obtained as a result of dividing a crossing region where said column direction wire bunch and said row direction wire bunch cross each other are specified, in a plan view, a plurality of dummy column block regions obtained as a result of dividing a crossing region where said dummy column direction wire bunch and said row direction wire bunch cross each other are specified, in a plan view, a plurality of dummy row block regions obtained as a result of dividing a crossing region where said dummy row direction wire bunch and said column direction wire bunch cross each other are specified, in a plan view, a plurality of patterns constituting said detection block regions, said dummy column block regions, and said dummy row block regions are specified, the number of said patterns in said dummy column block region or the number of said patterns in said dummy row block region is smaller than the number of said patterns in said detection block region.
