摘要： The present disclosure provides a display panel and a manufacturing method therefor, and a display device, and the display panel includes a first substrate and a second substrate disposed opposite to the first substrate; an organic light emitting layer disposed between the first substrate and the second substrate, wherein the organic light emitting layer includes a planar cathode layer; a planar cathode protection layer disposed on the cathode layer; and a first touch layer disposed on the cathode protection layer. With the technical solutions according to the present disclosure, the first touch layer is formed by evaporation processes just like the organic light emitting layer, so that the manufacture steps of the display panel are reduced as compared to forming the first touch layer by a photo etching process. Further, if the evaporation mask instead of the photo etching masks is used during the manufacture, the production cost is reduced.
