Title:
LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/138791
Kind Code:
A1
Abstract:
The present invention provides: a liquid crystal composition satisfying at least one property among properties such as high upper-limit temperature, low lower-limit temperature, low viscosity, adequate optical anisotropy, large negative dielectric anisotropy, large specific resistance, high stability to light, and high stability to heat; and an active matrix device including said composition. The liquid crystal composition contains, as a first additive, at least one compound selected from among a compound represented by formula (S) and a compound obtained by substituting at least one hydrogen in the compound represented by formula (S) with a monovalent group, and may contain a specific compound having a large negative dielectric anisotropy as a first component, a specific compound having a high upper-limit temperature or a low viscosity as a second component, and a specific compound having a polymerizable group as a second additive.
