1. A display apparatus with a touch sensor function comprising:

  • a first substrate having a common electrode;

    a second substrate arranged to face the first substrate;

    a display section disposed between the first substrate and the second substrate; and

    a touch sensor that detects a touch position on a touch surface disposed on the side of the first substrate or on the side of the second substrate, whereinthe second substrate has a plurality of data lines arranged in a row direction,a plurality of gate lines arranged in a column direction substantially perpendicular to the data lines,a plurality of pixel electrodes each arranged in a pixel region surrounded by a pair of neighboring data lines and a pair of neighboring gate lines, anda plurality of thin film transistors each arranged in the plurality of pixel electrodes and electrically connected to the pixel electrode, the data line, and the gate line, andthe touch sensor has a potential increase rate detection unit that detects a potential increase rate upon charging each of the pixel regions and detects a position of the pixel region whose potential increase rate detected by the potential increase rate detection unit falls outside a predetermined range as the touch position.
