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, wherein the bottom edge is a lower edge of the first substrate when the first substrate is placed vertically; 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 the extending direction of the at least one groove path runs parallel to the first substrate;
wherein a liquid crystal material in the liquid crystal layer is operative to diffuse 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 a plurality of groove paths arranged in parallel, the plurality of groove paths being created by curving inwards of a surface of the planarization layer adjacent to the liquid crystal layer;
wherein a width of each of the plurality of groove paths is less than or equal to a depth of the groove path, and an included angle between the extending direction of the groove path and the bottom edge is 90 degrees.
