Abstract
According to an aspect, a touch detecting device includes: a first drive area and a second drive area each including drive electrodes and detection electrodes, the drive electrodes extending in a first direction, being arrayed in a second direction intersecting with the first direction, and being applied with a drive signal, the detection electrodes extending in the second direction, being arrayed in the first direction, and outputting a detection signal. Application of the drive signal to the drive electrodes in the second drive area is stopped at a timing to apply the drive signal to the drive electrodes arranged in a first predetermined area included in the first drive area, and application of the drive signal to the drive electrodes in the first drive area is stopped at a timing to apply the drive signal to a second predetermined area included in the second drive area.
