摘要:
The present invention relates to a nematic liquid crystal composition useful as a liquid crystal display material and showing a negative value of dielectric anisotropy (Δ∈), and to a liquid crystal display device using the liquid crystal composition.The present invention provides a liquid crystal composition which causes little dropping marks during manufacture without degrading characteristics, such as dielectric anisotropy, viscosity, an upper limit temperature of a nematic phase, γ1, and the like, and image sticking of a display device.The liquid crystal display device of the present invention has excellent fast response, the characteristic of causing little image sticking, and the characteristic of causing little dropping marks due to its manufacture, and are thus particularly useful for VA-mode and PSVA-mode liquid crystal display devices for active matrix driving and can be applied to liquid crystal display devices such as liquid crystal TV, a monitor, and the like.
