Abstract: Disclosed is to provide a touch display device and a method of manufacturing the same, in which a compensation pattern is formed in a portion where a stepped structure and touch lines intersect each other in the process of arranging the touch lines on a touch display panel, so that a residual film of the touch lines, which may be generated due to a step, can be removed. By removing the residual film of the touch lines, it is possible to prevent a phenomenon in which a short circuit of adjacent touch lines occurs during the process of arranging the touch lines. Through this, it is possible to provide a touch display panel capable of reducing a defective rate during the process of arranging the touch lines.
