Abstract: A touch display device is provided, which includes a substrate, multiple touch electrodes arranged in an array on the substrate, and multiple touch lines on the substrate. The touch lines are arranged in a layer different from a layer in which the touch electrodes are positioned. The touch electrodes are arranged corresponding to the touch lines respectively. Each touch line is arranged parallel to a column direction of the touch electrodes. Each touch line includes a signal transmission portion. One end of the signal transmission portion of each touch line is connected to a corresponding one of the touch electrodes, another end of the signal transmission portion of each touch line is extended in a same direction to outside an area where the touch electrodes are positioned. Such configuration reduces a risk of short-circuiting between the touch lines and data lines in the same layer to ensure good production yields.
