Title:
LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/021838
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a liquid crystal composition which has a negative dielectric constant anisotropy (Δε), a large refractive index anisotropy (Δn), a high nematic-isotropic liquid phase transition temperature (TN
I), a low solid-nematic phase transition temperature (TCN), a sufficiently low rotational viscosity (γ1) and a large elastic constant (K33); and a liquid crystal display device using the same of VA-, FFS- or IPS-type, etc., which has a high response speed and a high VHR as well as an excellent low-temperature storage stability and shows no or very little display defect. According to the present invention, the above problem is solved by a liquid crystal composition which comprises compounds represented by general formulae (S1), (S2) and (S3).
