Title:
LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2017/010281
Kind Code:
A1
Abstract:
Provided is a liquid crystal composition which satisfies at least one property among properties such as a high upper-limit temperature, low lower-limit temperature, low viscosity, appropriate optical anisotropy, large negative dielectric anisotropy, high specific resistance, high stability against ultraviolet light, and high stability against heat, or which has an appropriate balance between at least two of these properties. Provided is an AM element which has properties such as a short response time, large voltage retention rate, low threshold voltage, large contrast ratio, and long service life. The composition 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 low viscosity as a second component, a specific compound having a negative dielectric anisotropy as a third component, or a specific compound having a polymerizable group as an additive component.
