Display Panel, Manufacturing Method Therefor, and Display Device

A method for manufacturing a display panel, comprising:

• providing a substrate structure, wherein the substrate structure comprises:
• a substrate comprising a first area for forming a hole of a display area,
• a driving circuit layer located on one side of the substrate and comprising a thin film transistor,
• a trace located on one side of the driving circuit layer away from the substrate and connected to the thin film transistor,
• one or more separators surrounding the first area and located on the one side of the driving circuit layer away from the substrate, wherein at least one separator of the one or more separators comprises a first separation material layer and a second separation layer located on one side of the first separation material layer away from the driving circuit layer, and
• a planarization layer located on one side of the driving circuit layer away from the substrate and covering the trace, the planarization layer not overlapping with the one or more separators;
• forming an anode material layer covering the substrate structure;
• and
• etching the anode material layer and at least one side surface of the first separation material layer to form an anode and a first separation layer, wherein the anode is connected to the trace through a via hole penetrating through the planarization layer, and an orthographic projection of one surface of the first separation layer away from the substrate on the substrate is within an orthographic projection of the second separation layer on the substrate.
