1. A touch detecting function display apparatus comprising:

  • a plurality of common driving electrodes that are disposed in parallel so as to extend in one direction;

    a display element that performs display based on a pixel signal and a display driving signal;

    a touch detection element that detects an external approaching object based on a touch detection driving signal; and

    a scanning driving unit that performs first scanning driving for sequentially applying the display driving signal to the plurality of common driving electrodes in a time division manner and second scanning driving for sequentially applying the touch detection driving signal to the plurality of common driving electrodes in a time division manner,wherein the scanning driving unit performs the second scanning driving at a scanning speed higher than that of the first scanning driving, and applies the display driving signal to an overlapping common driving electrode when the common driving electrode selected as a target of the first scanning driving overlaps with the common driving electrode selected as a target of the second scanning driving.
