Title:
LIQUID-CRYSTAL COMPOSITION AND LIQUID-CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/168721
Kind Code:
A1
Abstract:
Provided are: a polymerizable composition containing a polymerizable compound which has adequate polymerizability, attains a high conversion, and has high solubility in liquid-crystal compositions; and a liquid-crystal display element including the polymerizable composition. The polymerizable composition is a nematic liquid-crystal composition containing a maleimide compound as a first additive and having negative dielectric anisotropy. The polymerizable composition may contain a specific liquid-crystalline compound having a large value of negative dielectric anisotropy as a first component, a specific liquid-crystalline compound having a high upper-limit temperature or a low viscosity as a second component, and a polymerizable compound having a polar group as a second additive. The liquid-crystal display element includes the polymerizable composition.
