  • Publication number: 20230265345
    Abstract: A liquid crystal composition containing a polymerizable compound and an application of the liquid crystal composition. The liquid crystal composition comprises a nematic phase liquid crystal composition and at least contains one or more polymerizable compounds represented by general formula (I). Compared with existing liquid crystal compositions, the polymerizable compound in the liquid crystal composition has the advantages of faster polymerization rate, smaller pretilt angle change, higher conversion rate, and less residue, the problem that existing PSVA-type liquid crystal display is bad is mitigated to a large extent, the amount of pretilt angle change is reduced, and the area Mura problem is solved.
