Abstract

An elastomeric material, a color filter substrate and a liquid crystal panel are disclosed. The elastomeric material is prepared by subjecting a mixture of a siloxane side-chain liquid crystal elastomer, a polymerizable liquid crystalline monomer and a photoinitiator to UV irradiation to induce polymerization. The color filter substrate comprises a sealant and a pixel area, with a retaining ring disposed therebetween, wherein the retaining ring is prepared from the siloxane side-chain liquid crystal elastomer or the elastomeric material. The liquid crystal panel is prepared by assembling and aligning, under vacuum, an array substrate and the color filter substrate. By applying a ring of the elastomeric material having a network structure between the sealant and the pixel area according to the invention, it is possible to effectively prevent the impact of liquid crystal on the sealant during cell assembly and alignment, such that the undesirable phenomenon like penetration is minimized.
