Abstract
A touch display panel and a method for manufacturing the same are provided. The method includes: forming touch lines, an insulating layer and first electrodes above a substrate, the insulating layer covers the touch lines and is provided with at least one through-hole, the first electrodes are at a side of the insulating layer distal from the touch lines; forming barrier walls in each through-hole, and at a predetermined position in an interval between the first electrodes; forming a light emitting layer and a second electrode layer at a side of the light emitting layer distal from the substrate; removing the barrier walls, portions of the light emitting layer and the second electrode layer above the barrier walls, remaining portions of the second electrode layer form touch electrodes; forming an electrical conductive structure in each through-hole for coupling one touch line to one touch electrode.
