Abstract
A blue phase liquid crystal composite material and a liquid crystal display comprising the same, can solve the problem of small Kerr constant of the current blue phase liquid crystal and the liquid crystal display comprising the same. The blue phase liquid crystal composite material of the present disclosure is produced by the photo polymerization of the components comprising: a parent blue phase liquid crystal, a benzyne compound, a chiral compound, a photo-polymerizable monomer, and a photoinitiator. The blue phase liquid crystal composite material of the present disclosure has the advantages of large Kerr constant, low voltage, high contrast, rapid response to electric field, good stability, and the like.
