    Abstract: It is a method for manufacturing a liquid crystal display device in which an anchoring force causing liquid crystal molecules to be vertically aligned can be exerted sufficiently. A liquid crystal display device (1) including two substrates AM and CF and a liquid crystal layer (4) sandwiched therebetween can be manufactured. The liquid crystal display device manufacturing method includes: a first step of subjecting a surface of one of the substrates AM and CM that is to be in contact with the liquid crystal layer (4) to hydrophilization treatment; and a second step of disposing the two substrates AM and CF so as to face each other such that the two substrates are in contact with a liquid crystal composition containing liquid crystal molecules and an alignment aid having a polar group and having the function of causing the liquid crystal molecules to be aligned spontaneously.

    Abstract: There is provided a liquid crystal composition having the following properties without reductions in refractive index anisotropy (Δn) and nematic phase-isotropic liquid phase transition temperature (Tni): sufficiently small viscosity (η), sufficiently small rotational viscosity (γ1), a large elastic constant (K33), and negative dielectric anisotropy (Δ∈) with a large absolute value. There is also provided a liquid crystal display device of, for example, a VA type in which such a liquid crystal composition is used and which has a high response speed and excellent display quality with defective display being eliminated or reduced. The liquid crystal display device using the liquid crystal composition of the present invention is useful as an active-matrix liquid crystal display device and can be used in liquid crystal display devices of, for instance, a VA mode and PSVA mode.

    Abstract translation: 提供具有以下性质的液晶组合物，其折射率各向异性（Δn）和向列相各向同性液相转变温度（Tni）不降低：足够小的粘度（η），足够小的旋转粘度（γ1），大的 弹性常数（K33）和负介电各向异性（Δε），绝对值大。 还提供了例如使用这种液晶组合物并且具有高响应速度和优异的显示质量的VA型液晶显示装置，其中不良显示被消除或减少。 使用本发明的液晶组合物的液晶显示装置可用作有源矩阵液晶显示装置，并且可以用于例如VA模式和PSVA模式的液晶显示装置中。
