1. A display panel, with a non-display area, a central display area, and a peripheral display area between the non-display area and the central display area, the display panel comprising:
an array substrate;
a counterpart substrate, arranged opposite to the array substrate; and
a liquid crystal layer, provided between the array substrate and the counterpart substrate;
wherein the counterpart substrate comprises a base substrate and a meta-surface structure layer, the meta-surface structure layer is disposed on one side of the base substrate close to the liquid crystal layer and is located in the peripheral display area, and at least part of light emitted from the peripheral display area is deflected by the meta-surface structure layer and then emerges from the non-display area;
wherein the peripheral display area comprises a first peripheral sub-display area and a second peripheral sub-display area between the central display area and the first peripheral sub-display area;
the meta-surface structure layer comprises a plurality of meta-surface structure units, each of the meta-surface structure units comprises a deflection angle relative to a first direction, the first direction is a direction perpendicular to a second direction, the second direction is a direction along a boundary line between the central display area and the second peripheral sub-display area;
along a direction from the second peripheral sub-display area to the first peripheral sub-display area, the deflection angles of the meta-surface structure units located in the first peripheral sub-display area gradually increase; and
along a direction from the first peripheral sub-display area to the second peripheral sub-display area, the deflection angles of the meta-surface structure units located in the second peripheral sub-display area gradually increase.
