Claim 13:
14. The detecting device according to claim 13, having a first period and a second period that differ in a coupling state of the switch elements, wherein
in the first period,
the switch elements cause the first drive electrode to be decoupled from the second drive electrode, and
the drive signal supply circuit supplies the first voltage signal to at least one or more of a plurality of the first drive electrodes and supplies the second voltage signal to at least one or more of a plurality of the second drive electrodes, and

in the second period,
the drive signal supply circuit stops supplying the first voltage signal to the first drive electrode and supplying the second voltage signal to the second drive electrode, and
the switch elements couple the first drive electrode and the second drive electrode.
