Title:
LIQUID-CRYSTAL COMPOSITION AND LIQUID-CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/003982
Kind Code:
A1
Abstract:
Provided are: a liquid-crystal composition which satisfies at least one of properties such as a high upper-limit temperature, a low lower-limit temperature, a low viscosity, adequate optical anisotropy, and high negative dielectric anisotropy, or has an adequate balance between at least two of these properties; and an AM element including the composition. The liquid-crystal composition comprises a specific compound having high dielectric anisotropy as a first ingredient and a specific compound having either a low viscosity or a high elastic constant as a second ingredient and may further contain a specific compound having high dielectric anisotropy as a third ingredient, a specific compound having a high upper-limit temperature as a fourth ingredient, or a specific compound having a polymerizable group as a first additive.
