Display panel and display device

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 a plurality of groups of raised structures arranged on a surface of the planarization layer adjacent to the liquid crystal layer;
• wherein the plurality of groups of raised structures are arranged in sequence starting from the bottom edge of the first substrate in a direction perpendicular to the bottom edge;
• wherein each group of raised structures comprises a plurality of raised structures spaced in sequence along the direction of the bottom edge, wherein the raised structures are each “Y” shaped or “I” shaped, and a respective groove path is defined between every two adjacent raised structures.

A display device, comprising a driving circuit and a display panel, wherein the driving circuit is configured to drive the display panel to display;

• wherein the display panel comprises 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 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.
