Display Panel and Method for Manufacturing the Same, Display Device and Tiled Display Device

A method for manufacturing a display panel, comprising:

• providing a substrate, wherein the substrate includes a display surface and a non-display surface that are opposite, and a plurality of side faces connected to the display surface and the non-display surface;
• at least one side face in the plurality of side faces is a selected side face;
• the display surface includes a first bonding area, the non-display surface includes a second bonding area, and the first bonding area and the second bonding area are both proximate to the selected side face and disposed oppositely;
• forming a plurality of first bonding electrodes arranged side by side and at intervals on the display surface of the substrate;
• the plurality of first bonding electrodes being disposed in the first bonding area;
• forming a plurality of connecting leads arranged side by side and at intervals, wherein each connecting lead includes a first portion located in the first bonding area, a second portion located on the selected side face and a third portion located in the second bonding area;
• the first portion of each connecting lead is electrically connected to a first bonding electrode;
• providing an electrode carrier plate and forming a plurality of second bonding electrodes arranged side by side and at intervals on the electrode carrier plate;
• and
• providing the electrode carrier plate provided with the plurality of second bonding electrodes thereon on a side of the non-display surface, and connecting each second bonding electrode to a third portion of a connecting lead.
