1. A touch display device comprising:

  • a touch panel configured to display an image, the touch panel including a plurality of subpixels arranged between a first substrate and a second substrate, and a plurality of touch sensors arranged in units of a certain number of subpixels;

    an elastic layer on the second substrate;

    a display driver configured to supply image signals to the plurality of subpixels, respectively; and

    a touch driver configured to supply a touch driving signal to the plurality of touch sensors, sense a touch position of a touch based on a capacitance variation of a first touch sensor among the plurality of touch sensors, supply the touch driving signal to the first touch sensor and a plurality of second touch sensors surrounding the first touch sensor among the plurality of touch sensors, and sense a touch pressure of the touch position based on capacitance variations of the first touch sensor and the plurality of second touch sensors.
