| description | Disclosed are a polymer-stabilized liquid crystal composition and the use thereof. The composition comprises one or two polymerizable compounds represented by general formula I: (I), and further comprises a negative dielectric anisotropy liquid crystal composition, wherein the negative dielectric anisotropy liquid crystal composition has a dielectric anisotropy of Δε≤−1.5; and the added amount of the polymerizable compound(s) represented by general formula I is 0.1-0.5% of the total mass of the negative dielectric anisotropy liquid crystal composition. A polymer film formed after the polymerization of the provided liquid crystal composition containing the polymerizable compound(s) has a very good uniformity, such that the problem of liquid crystal displays having poor display can be improved. Moreover, an alignment film formed after the polymerization of the polymerizable liquid crystal composition has an excellent alignment force, and can improve residual image problems caused by an insufficient alignment force in a PSVA liquid crystal display. The provided liquid crystal composition containing the polymerizable compound(s) can realize an adjustable response speed, and can in turn meet the requirements of different technical process conditions. |
