| 摘要 |
The present invention suppresses, without increasing manufacturing costs, diffusion of a conductive member forming wires and migration caused thereby. A touch panel includes a plurality of X electrode wires respectively connected to a plurality of X electrodes formed on a substrate, a plurality of Y electrode wires respectively connected to a plurality of Y electrodes formed on the substrate, and shield wires provided, at one end of the substrate, 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 respective wires of one of the X electrode wires and 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.
