Abstract
A touch display device can include a touch panel having 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 for supplying image signals to the plurality of subpixels, respectively; and a touch driver for supplying a touch driving signal to the plurality of touch sensors and sensing a touch position and a touch pressure which is applied when a touch is input to the touch panel, based on a capacitance variation of each of the plurality of touch sensors.
