1. A display panel, comprising:
a base substrate; wherein the base substrate is a silicon substrate;
a plurality of light-emitting devices on the base substrate, wherein the light-emitting device comprises:
a first electrode and a second electrode arranged in a stacked manner, and
a light-emitting functional layer between the first electrode and the second electrode; and
barrier structures on a film layer between the light-emitting functional layer and the base substrate; wherein the barrier structure comprises a dielectric layer and a conductive layer arranged in a stacked manner, the dielectric layer is in contact with the light-emitting functional layer, a surface of a side of the dielectric layer close to the light-emitting functional layer is a rough surface, the first electrode is in contact with a surface of a side of the base substrate close to the light-emitting functional layer, the barrier structures are arranged on the side of the base substrate close to the light-emitting functional layer, an orthographic projection of the barrier structure on the base substrate is between orthographic projections of light-emitting devices, adjacent to the barrier structure, on the base substrate, and the orthographic projection of the barrier structure on the base substrate dose not overlap an orthographic projection of the first electrode on the base substrate;
wherein the barrier structure is configured to generate, under control of an electrical signal, an electric field in a direction perpendicular to a plane where the base substrate is located.
