1. A display panel comprising a first substrate, a second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate;
wherein the first substrate comprises a first base and a planarization layer disposed on a side of the first substrate adjacent to the liquid crystal layer;
wherein a side of the planarization layer adjacent to the liquid crystal layer comprises a textured structure, the textured structure comprising at least one groove path;
wherein the first substrate further comprises a bottom edge; an extending direction of the at least one groove path forms an included angle with the bottom edge, the included angle being greater than or equal to 45 degrees and less than or equal to 135 degrees;
wherein a liquid crystal material in the liquid crystal layer diffuses through the at least one groove path along an extending direction of the at least one groove path based on a capillary phenomenon;
wherein the textured structure comprises at least two raised structures, which are of an elongated shape and are arranged on a surface of the planarization layer adjacent to the liquid crystal layer;
wherein a respective groove path is defined between every two adjacent raised structures;
wherein a length direction of each of the at least one raised structures is parallel to the extending direction of the at least one groove path;
wherein a width of each of the at least one groove path is less than or equal to a thickness of each of the at least two raised structures measured in a direction perpendicular to the first base;
wherein the textured structure comprises a plurality of raised structures, which are evenly spaced and arranged in parallel, and wherein a respective groove path is defined between every two adjacent raised structures;
wherein each of the plurality of raised structures extends from the sealant adjacent to the bottom edge of the first substrate to the sealant facing away from the bottom edge of the first substrate, wherein the included angle between the extending direction of the at least one groove path and the bottom edge is 90 degrees.
