<p>A touch display device according to an embodiment of the present invention comprises a first substrate having a pixel electrode, a common electrode, a color filter, and a touch column spacer; and a second substrate bonded to the first substrate while sandwiching a liquid crystal layer therebetween. The second substrate includes a touch sensing unit which includes Tx lines arranged in a first direction and Rx lines arranged in a second direction intersecting the first direction, and determines a touch position by a change in capacitance through sensing pulse voltages of the Tx lines from the Rx lines; and a touch sensor which is disposed on the touch sensing unit and determines a touch pressure strength by the change in capacitance with the common electrode covering the touch column spacer. The touch sensor unit and the touch sensor are disposed between the first substrate and the second substrate.</p> |
