Display panel and method for manufacturing the same, display device

A method for manufacturing a display panel, comprising:

• manufacturing a substrate;
• manufacturing a packaging layer on the substrate, and forming a first slope on an edge of a first side of the packaging layer;
• manufacturing touch lines on a side of the packaging layer away from the substrate, so that an extending direction of at least a portion of the touch lines is crossed with an extending direction of the edge of the packaging layer with the first slope;
• the manufacturing the touch lines on the side of the packaging layer away from the substrate comprises:
• manufacturing a plurality of first lines, so that an orthographic projection of at least a portion of the first lines on the substrate is not overlapped with an orthographic projection of a portion of the packaging layer with the first slope on the substrate;
• manufacturing a first insulating layer on a side of the first lines away from the substrate, including manufacturing vias in the first insulating layer, so that a plurality of second lines to be manufactured are electrically coupled to the first lines through the vias in the first insulating layer;
• manufacturing the plurality of second lines on a side of the first insulating layer away from the substrate.
