摘要： The present disclosure relates to a method for manufacturing a touch display panel. The method includes providing a substrate film layer; forming a display functional film layer on the substrate film layer; forming an encapsulation film layer on a side of the display functional film layer away from the substrate film layer; forming a touch functional film layer on a side of the encapsulation film layer away from the display functional film layer; and after the touch functional film layer is formed, removing all film layers which include at least the substrate film layer and are located at opening areas to form through holes.
