Abstract: Embodiments of the present disclosure relate to a touch display device and a display panel. The touch display device comprises a display panel in which a plurality of X-touch electrodes arranged in a first direction are electrically connected to form a X-touch electrode line and a plurality of X-touch electrode lines arranged in parallel to receive a plurality of touch driving signals, and a plurality of Y-touch electrode lines are extended to a second direction to transmit a plurality of touch sensing signals; and a touch driving circuit for supplying the plurality of touch driving signals to the plurality of X-touch electrode lines and for sensing a touch by detecting the plurality of touch sensing signals from the plurality of Y-touch electrode lines, wherein a plurality of X-touch lines transmitting the plurality of touch driving signals to the plurality of X-touch electrode lines are extended in the second direction and are alternately connected to the plurality of X-touch electrodes through a plurality of touch contact holes to electrically connect a plurality of X-touch electrodes constituting a same X-touch electrode line.
