1. A display panel, comprising:
a display substrate, and
at least one light emitting angle adjustment structure arranged on a light emitting side of the display substrate;
wherein the at least one light emitting angle adjustment structure comprises an electrode structure and an electrical control material layer which are disposed in a laminated manner;
wherein the electrical control material layer is configured to form a convex lens structure or a concave lens structure under an action of an electric field, and is of a flat mirror structure when there is no electric field; and
the electrode structure is configured to form the electric field when a voltage is applied, to enable the electrical control material layer to form the convex lens structure or the concave lens structure under the action of the electric field;
wherein the electrode structure comprises a first electrode layer, an insulating layer, and a second electrode layer which are disposed in a laminated manner;
wherein the electrode structure is arranged on a side, close to the display substrate, of the electrical control material layer; or
the electrode structure is arranged on a side, away from the display substrate, of the electrical control material layer.
