Mixture for liquid crystal medium and liquid crystal display using the same

摘要

The present invention provides a mixture for liquid crystal medium and a liquid crystal display using the same. The mixture for liquid crystal medium comprises: at least one anisotropic liquid crystal material and a polymerizable monomer which will polymerize under UV irradiation. The weight percentage of the polymerizable monomer accounts for 0.1% to 1% of the total mixture for liquid crystal medium. In the mixture for liquid crystal medium and a liquid crystal display using the same according to the present invention, by using a polymerizable monomer which will polymerize under UV irradiation and the appropriate content ratio, the polymer bump with small size and good uniformity can be obtained within the mixture for liquid crystal medium after the polymerization, which avoids the bad liquid crystal alignment and the light spot occurred at the dark state of the liquid crystal panel, and then increases the response rapid of the liquid crystal panel to obtain high contrast ratio and stable mass production.
