  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.

  本发明提供了一种含有可聚合化合物的液晶组合物，用于生产 PSA 或 PSVA 型液晶显示元件，该液晶组合物具有优异的响应性能和令人满意的前倾角，且残留单体较少，不会出现或很少出现由低电压保持比（VHR）等引起的对准缺陷和显示缺陷等问题。此外，还提供了一种使用该液晶组合物的液晶显示元件。根据本发明的液晶组合物是一种液晶组合物，它具有足够低的粘度（η）、足够低的旋转粘度（γ1）和较大的弹性模量（K33），同时不会降低折射率各向异性（Δn）和向列相-各向异性液相转变温度（Tni），也不会提高固相-向列相转变温度（Tcn）。使用这种液晶成分的液晶显示元件能令人满意地获得前倾角，并具有高电压保持比（VHR）和高速响应。这样，就得到了一种没有或较少对准缺陷和显示缺陷（如图像粘连）、具有高显示质量和高响应速度的液晶显示元件。
