Patent ID: 8801965

Claim:
A liquid crystal medium composition, comprising: a negative liquid crystal material, a polymerizable monomer, a sensitizer, and stabilizer; the sensitizer being an organometallic complex that has an amount of 0.01%-5% of total mass of the liquid crystal composition and absorbing ultraviolet light having a wavelength of 300-450nm, the sensitizer comprises one or more sensitizers represented by the following formula: wherein in the formula, M represents central atom that is a metal atom and is specifically Ru, Os, Pt, Cu, Fe, Zn, or Ti; ED, ring Z1, and ring Z2 are each an organic ligand or a coordination molecule with n1, n2, and n3 being integers of 0-8, but not all zero, wherein ED is selected from a group consisting of S═C═N—, NC—, and R—S—, where R of R—S— is H atom or C1-12 linear or branched alkyl, one or more of non-adjacent CH 2 of the linear or branched alkyl is substitutable by O atom; ring Z1 represents a five-membered heterocyclic ligand, which is selected from a group consisting of a saturated structure, an unsaturated structure, and a five-membered heterocyclic ring containing an aromatic ring and in which X is heteroatom and is specifically one or more of N, O, and S, R1 represents a substituted moiety on the ring Z1, which is H, or C1-12 linear alkyl or branched alkyl, in which one or more of non-adjacent CH 2 on the linear alkyl or branched alkyl is substitutable by O atom, substituted moiety R1 comprises other ring structures containing heteroatom, k1 is the number of substituted moiety R 1 , which is an integral of 0-5; and ring Z2 represents a six-membered heterocyclic ligand, which is selected from a group consisting of a saturated structure, an unsaturated structure, or a six-membered heterocyclic ring containing aromatic ring and in which Y is heteroatom and is specifically one or more of N, O, and S, R 2 represents a substituted moiety on the ring Z2, which is H, or C1-12 linear alkyl or branched alkyl, in which one or more of non-adjacent CH 2 on the linear alkyl or branched alkyl is substitutable by O atom, substituted moiety R 2 comprises other ring structures containing heteroatom, k2 is the number of substituted moiety R 2 , which is an integral of 0-5.
