1. A display panel, comprising:
a display substrate, wherein at least one side of the display substrate is provided with a pad region, a plurality of gold fingers are arranged in the pad region, and the gold fingers extend to a side edge of the display substrate where the pad region is located;
an opposing substrate, wherein the opposing substrate is arranged opposite to the display substrate, and an orthographic projection of the opposing substrate on the display substrate covers the pad region;
frame sealant, wherein the frame sealant seals an area between the display substrate and the opposing substrate, and the pad region is located on an outer side of the area sealed by the frame sealant;
a flexible buffer layer, wherein the flexible buffer layer is filled between the display substrate and the opposing substrate and is located on the outer side of the area sealed by the frame sealant, and an orthographic projection of the flexible buffer layer on the display substrate covers the gold fingers; and
a conductive part, wherein the conductive part is located on a side face of the display substrate close to the pad region, and the conductive part is electrically connected with the gold fingers.
