Title:
NEMATIC LIQUID-CRYSTAL COMPOSITION AND LIQUID-CRYSTAL DISPLAY ELEMENT OBTAINED USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/136315
Kind Code:
A1
Abstract:
Provided is a liquid-crystal composition characterized by comprising one or more compounds represented by general formula (I) as a first component and one or more compounds, as a second component, selected from the group consisting of compounds represented by general formula (II) and by having a dielectric anisotropy (∆ε) at 25ºC of -2.0 or less. The liquid-crystal composition has a negative dielectric anisotropy, large refractive-index anisotropy, and low viscosity. Also provided is a liquid-crystal display element which has a high contrast and high-speed responsiveness and, simultaneously therewith, has excellent display quality that is free from image persistence and display failures.
