<P>PROBLEM TO BE SOLVED: To provide a technique to reduce excess parasitic capacity on each leader wiring and each detection wiring simultaneously in a touch screen. <P>SOLUTION: A touch screen includes: a detection area in which a plurality of detection column wiring are arranged in a column direction and a plurality of detection row wiring are arranged in a row direction so that the column wiring and the row wiring three-dimensionally intersect with each other; a terminal electrically connectable to an external device; and a plurality of leader wiring which connect the plurality of detection row wiring and detection column wiring to the terminal. The plurality of leader wiring are arranged adjacently to each other and in a circular way, provided with dummy leader wiring which is arranged outside the outermost leader wiring among the plurality of adjacently-arranged leader wiring and of which one end is electrically connected to the terminal. The outer periphery of the detection area is adjacently enclosed by the leader wiring or the dummy leader wiring. <P>COPYRIGHT: (C)2013,JPO&INPIT |
