Claim Text:
1. A display device with a touch detecting function comprising: a plurality of pixel electrodes arranged in a display area; a plurality of drive electrodes arranged opposed to the pixel electrodes; a control device configured to apply a drive voltage for display between the plurality of pixel electrodes and the plurality of drive electrodes, the control device including a touch detection electrode opposed to the drive electrodes; wiring for touch that is arranged in the peripheral area and that is configured to supply a drive signal for touch to the plurality of drive electrodes; and a selection switch configured to select the drive electrodes to be coupled to the wiring for touch, wherein the drive electrode scanning unit includes a plurality of transfer circuits configured to supply the drive signal for touch, wherein the transfer circuits include wherein a transfer circuit output is transferred sequentially through the transfer circuits started by the scanning start signal as a trigger, wherein the second transfer circuit supplies the transfer circuit output as an idle transfer signal to the first transfer circuit next to the second transfer circuit, and wherein when triggered by a high level of the transfer circuit output and a high level of the drive electrode selection signal, the first transfer circuit outputs the high level of the transfer circuit output to control the selection switch, in synchronization with the high level of the drive electrode selection signal.
