Display panel and method for manufacturing the same, display device and tiled display apparatus

A method for manufacturing a display panel, comprising:

• providing a substrate, wherein the substrate includes a first surface and a second surface that are opposite, and a plurality of side surfaces connecting the first surface and the second surface, at least one side surface in the plurality of side surfaces is a selected side surface;
• and the second surface includes an isolation region;
• and
• forming a plurality of connection wires on the first surface, the second surface and the selected side surface of the substrate, and forming a first electrostatic discharge structure on the second surface, wherein the plurality of connection wires are arranged side by side at intervals;
• each connection wire in the plurality of connection wires includes a first-segment wire, a second-segment wire and a third-segment wire connected in sequence, the first-segment wire is located on the first surface, the second-segment wire is located on the selected side surface, and the third-segment wire is located on the second surface;
• the first electrostatic discharge structure is located on the second surface, and the first electrostatic discharge structure is arranged on a side of a plurality of third-segment wires of the plurality of connection wires away from the selected side surface;
• the isolation region is located between the plurality of third-segment wires and the first electrostatic discharge structure, and the isolation region is configured to separate the plurality of connection wires from the first electrostatic discharge structure, so that the plurality of connection wires are electrically isolated from the first electrostatic discharge structure.
