Patent ID: 8753537

Claim:
A mixture for liquid crystal medium comprising: a liquid crystal material and a polymerizable monomer which will polymerize under UV irradiation, the liquid crystal material comprising an alkenyl compound which is stable to the polymerization reaction during the polymerization of the polymerizable monomer, the weight percentage of the polymerizable monomer accounting for 0.1% to 1% of the total mixture for liquid crystal medium; the polymerizable monomer defined by the following structural formula: wherein, P represents a polymerizable group, which is selected from the group consisting of methacrylate group or acrylate group; m represents the number of the polymerizable groups Ps connected to the same aromatic ring, m represents 2 or 3; Y represents 1 or 2; R represents the alkyl containing number of carbon atoms from 1 to 12; wherein the Ps are not methacrylate group simultaneously.
