Claim Text:
1. A touchscreen covered by mesh-shaped wiring patterns of a row-directional line and a column-directional line being upper and lower two layers, wherein said row-directional line or said column-directional line has its width narrowed at a crossing portion where said row-directional line and said column-directional line cross each other, said row-directional line or said column-directional line includes a floating electrode provided to be adjacent to a region where said row-directional line and said column-directional line overlap each other in a planar view, said floating electrode is insulated from surrounding lines, said floating electrode including a disconnecting portion dividing said floating electrode, said floating electrode further including a first floating electrode of said mesh-shape formed at the same layer as that of said row-directional line, a second floating electrode of said mesh-shape formed at the same layer as that of said column-directional line, a column-directional dummy line of said mesh-shape formed at the same layer as that of said row-directional line, in the same region as that of the column-directional line in a planar view, and a row-directional dummy line of said mesh-shape formed at the same layer as that of said column-directional line, in the same region as that of the row-directional line in a planar view, wherein the mesh of said row-directional line and the mesh of said column-directional line are arranged as being complementarily displaced in a planar view, the mesh of said column-directional line and the mesh of said column-directional dummy line are arranged as being complementarily displaced in a planar view, the mesh of said row-directional line and the mesh of said row-directional dummy line are arranged as being complementarily displaced in a planar view, and the mesh of said first floating electrode and the mesh of said second floating electrode are arranged as being complementarily displaced in a planar view.
