Display panel, preparation method thereof, and liquid crystal display

A display panel comprising:

• a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer between the first substrate and the second substrate, and a polymerizable monomer arranged in the liquid crystal layer;
• wherein a plurality of polymer walls are arranged in the liquid crystal layer;
• the plurality of polymer walls are contacted with the first substrate and the second substrate, and a polymerization direction of the polymerizable monomer in the polymer wall is substantially perpendicular to a thickness direction of the polymer wall;
• wherein the plurality of polymer walls comprise a plurality of first polymer walls extending to a first direction and a plurality of second polymer walls extending to a second direction;
• the first direction and the second direction are substantially parallel to a surface of the first substrate;
• the plurality of the first polymer walls and the plurality of the second polymer walls are interlaced to form a grid shape, wherein each grid in the grid shape corresponds to a pixel;
• wherein the polymerizable monomer comprises at least one of acrylate, acrylate derivatives, methacrylate, methacrylate derivatives, cinnamate, coumarin, styrylpyridine, styryl phthalimidine, and diphenylacetylene.
