1. A touch display device comprising:
a display panel having disposed therein:
a plurality of X-touch electrode lines, which extend in a first direction and to which a touch driving signal is transmitted through a plurality of X-touch lines, an X-touch line of the plurality of X-touch lines being connected to an X-touch electrode line of the plurality of X-touch electrode lines, the X-touch electrode line being located in a non-square area; and
a plurality of Y-touch electrode lines, which extend in a second direction and transmit a touch sensing signal through a plurality of Y-touch lines, a Y-touch line of the plurality of Y-touch lines being connected to a Y-touch electrode line of the plurality of Y-touch electrode lines, the Y-touch electrode line being located in the non-square area; and
a touch driving circuit configured to supply the touch driving signal to the plurality of X-touch electrode lines and receive the touch sensing signal from the Y-touch electrode line to sense a touch,
wherein a plurality of overlapping areas in which at least some of the plurality of X-touch lines overlap at least some of the plurality of Y-touch lines are different from each other, a first overlapping area of the plurality of overlapping areas that is associated with the X-touch line and the Y-touch line having an area that is larger than respective areas of other overlapping areas associated with other X-touch lines and other Y-touch lines.
