  Provided is a liquid crystal composition that contains a polymerizable compound and is used for producing a PSA- or PSVA-type liquid crystal display element that has excellent response performance and a satisfactory pretilt angle and that contains less residual monomers, in which issues such as alignment defects and display defects caused by a low voltage holding ratio (VHR) or the like do not occur or rarely occur. Also provided is a liquid crystal display element that uses the liquid crystal composition. The liquid crystal composition according to the present invention is a liquid crystal composition that exhibits a sufficiently low viscosity (η), a sufficiently low rotational viscosity (γ1), and a large elastic modulus (K33) without decreasing the refractive index anisotropy (Δn) and the nematic phase-isotropic liquid phase transition temperature (Tni) and without increasing the solid phase-nematic phase transition temperature (Tcn). The liquid crystal display element that uses this liquid crystal composition satisfactorily obtains a pretilt angle and has a high voltage holding ratio (VHR) and high-speed response. Thus, a liquid crystal display element that has no or less alignment defects and display defects such as image sticking, and has high display quality and high response speed is obtained.
