<P>PROBLEM TO BE SOLVED: To suppress diffusion of a conductive member forming wires and migration caused thereby, without increasing manufacturing costs. <P>SOLUTION: A touch panel includes: a substrate; a plurality of X electrodes formed on the substrate; a plurality of Y electrodes formed on the substrate to respectively cross the plurality of X electrodes; a plurality of X electrode wires formed on the substrate and respectively connected to the plurality of X electrodes; and a plurality of Y electrode wires formed on the substrate and respectively connected to the plurality of Y electrodes. The touch panel includes, on arbitrary one side of the substrate, shield wires provided between a region where the plurality of X electrode wires are formed and a region where the plurality of Y electrode wires are formed. A pulse voltage changing between a GND voltage and a Va voltage higher than the GND voltage is supplied to each of either the X electrode wires or the Y electrode wires. A (Va/2) voltage is supplied to the shield wires in a period in which detection of a touch position is performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
