Title:
NEMATIC LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/102076
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a liquid crystal composition which exhibits sufficiently high refractive index anisotropy (Δn) and a sufficiently high nematic phase-isotropic liquid phase transition temperature (Tni), a sufficiently low viscosity (η), a sufficient low rotational viscosity (γ1), a high elastic constant (K33), and either a large dielectric anisotropy (Δε) or a negative Δε having a large absolute value and which exhibits little reliability degradation even after UV irradiation; and a liquid crystal display device which uses the liquid crystal composition and which exhibits excellent display quality and a high response speed. As a result of studies which have been earnestly made with effort by the inventors of the present invention, it is found that the problem can be solved by: a polymerizable-compound-containing liquid crystal composition which comprises both a polymerizable compound having a specific chemical structure and a nonpolymerizable liquid crystal compound and in which the polymerizable compound is contained at a specific ratio; or a liquid crystal display device using the same. Thus, the present invention has been accomplished.
