Abstract:
A touch display device and a display panel uniformly distributing capacitances between the touch lines and the touch electrodes are provided. The device includes a display panel in which a plurality of X-touch electrodes 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 to transmit a plurality of touch sensing signals, and a touch driving circuit. A plurality of X-touch lines transmit the touch driving signals connect together the plurality of X-touch electrodes constituting a same X-touch electrode line through a plurality of contact holes. Distances between at least one Y-touch electrode line and the plurality of contact holes through which the plurality of X-touch lines are electrically connected to the X-touch electrodes adjacent to the at least one Y-touch electrode line are uniform.
