Abstract: A reflective filter includes a first substrate provided with a first electrode, a second substrate provided with a second electrode, and a liquid crystal layer filled with a liquid crystal composition including cholesteric liquid crystals, wherein the reflective filter includes at least two reflective areas that reflect light of different colors. By applying an external electric field to align the liquid crystal molecules, ultraviolet light is used to induce a chiral compound to subject to chiral inversion, such that the division control of the reflective areas is realized in a same kind of a liquid crystal material matrix.

Abstract: A liquid crystal material, a liquid crystal display panel, and a manufacturing method thereof are provided. The liquid crystal material includes negative liquid crystal molecules and one or more thiol polymerizable monomers. The display panel uses a polymer film obtained by polymerization of a click chemistry reaction of a “thiol and double bond” system to anchor an orientation state of the liquid crystal molecules on the substrate surface, with few impurities and a low risk of image sticking displayed on the panel.
