Title:
LIQUID CRYSTAL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/124093
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a polymerizable liquid crystal composition that has a negative dielectric constant anisotropy (Δε), that satisfies low voltage drive properties, high-speed response, and display-ability in a wide temperature range typically required for liquid crystal compositions, and that has no or very few display defects when used in a liquid crystal display element; and a liquid crystal display element using the liquid crystal composition. This liquid crystal composition has a negative dielectric constant anisotropy (Δε) and comprises one or more polymerizable compounds and one or more compounds selected from compounds represented by general formulas (N-1), (N-2), and (N-3).
