The present invention discloses a liquid crystal composition for a polymer stabilized vertical alignment liquid crystal display (PS-VA LCD) and a liquid crystal display panel thereof; the liquid crystal composition comprises at least one type of negative liquid crystal material, a type of stabilizer and one or more type of reactive monomers; the structural formula of the reactive monomer consists of one benzene ring, two benzene rings or one naphthalene ring, the structure of two benzene rings is formed by connecting the two benzene rings directly or indirectly with a group, at least one polymerizable group is connected directly to the benzene ring and naphthalene ring, and at least one of polymerizable groups is an acrylate group. Reaction rate of the reactive monomer and uniformity of polymer bumps are improved by selecting polymerizable groups of the reactive monomer and controlling the content thereof to effectively solve quality issues of panels. |
