1. A display panel, comprising:
a base substrate comprising a through hole penetrating through the base substrate, an encapsulation region of the base substrate comprising an edge surrounding the through hole; and
a post spacer arranged between the edge of the encapsulation region surrounding the through hole and the through hole,
wherein the post spacer comprises a first portion made of metal and a post body made of an insulating material, a distance between the first portion and the base substrate is greater than a distance between the post body and the base substrate, and an area of an orthogonal projection of the first portion onto the base substrate is greater than an area of an orthogonal projection of the post body onto the base substrate;
a first metal layer arranged on the base substrate and an insulating layer arranged between the first metal layer and the base substrate, wherein the first metal layer and the first portion are arranged on a same layer and made of a same metal material, and the insulating layer and the post body are arranged on a same layer and made of the insulating material.
