摘要：
A display apparatus with a touch detection function, includes: a plurality of common drive electrodes disposed in parallel so as to extend in one direction; a display element displaying on the basis of a pixel signal and a display drive signal; a touch detection element detecting an external approaching object on the basis of a touch-detection drive signal; and a scan drive section performing first scan driving to apply the display drive signal to the plurality of common drive electrodes sequentially by time division and second scan driving having a scan speed different from a scan speed of the first scan driving to apply the touch-detection drive signal to the plurality of common drive electrodes sequentially by time division, wherein the scan drive section drives the common drive electrodes for each plurality of the electrodes in the first and the second scan driving.
