1. A liquid crystal display device comprising:

  • a liquid crystal panel for displaying an image supplied from outside;

    a driving section for driving the liquid crystal panel in accordance with a driving signal;

    a capacitive touch sensor for detecting a change in capacitance, the capacitive touch panel being provided so as to overlap the liquid crystal panel;

    a control section for scanning the capacitive touch sensor in accordance with a reference clock signal which is generated by an oscillation circuit provided in the liquid crystal display device;

    a counting section for counting a frequency of the driving signal;

    a determining section for determining whether or not the frequency of the driving signal is a predetermined value; and

    a changing section for changing, in a case where the determining section determines that the frequency of the driving signal is not the predetermined value, a frequency at which the capacitive touch sensor is scanned.
