1. A touch sensing device comprising:

  • a panel including pixels disposed in a matrix form defined by data lines and gate lines, the pixels including thin film transistors (TFTs);

    at least one touch sensor having a mutual capacitance;

    a sensor driving circuit configured to receive an electric charge from the mutual capacitance; and

    a display driving circuit configured to supply a first parasitic capacitance suppressing signal to the data lines and a second parasitic capacitance suppressing signal to the gate lines during a touch sensor driving period.
