Abstract
A liquid crystal medium composition of liquid crystal display includes: a negative liquid crystal material, reactive monomer, an initiator, and a stabilizer. The initiator functions to induce photo polymerization of the reactive monomer. The initiator has a molecular structure comprising aromatic rings, carbonyl groups connected to the aromatic rings, and substituted moieties connected to the aromatic rings. The initiator lowers the activation energy of chain initiation reaction of the polymerization of reactive monomer to allow the photo polymerization of the reactive monomer to take place in a wider wavelength range of 200-450 nm, so as to reduce the required intensity and luminance of ultraviolet light and to speed up the reaction of the reactive monomers and also to provide a uniform result of reaction, to reduce the destruction that the ultraviolet light causes on the material of alignment layer and the liquid crystal material, and to improve stability of the panel.
