Title:
LIQUID CRYSTAL COMPOSITION FOR LIGHT-SCATTERING LIQUID CRYSTAL DEVICE, LIGHT-SCATTERING LIQUID CRYSTAL DEVICE, AND SMART WINDOW
Document Type and Number:
WIPO Patent Application WO/2020/110364
Kind Code:
A1
Abstract:
The present invention pertains to: a liquid crystal composition for a light-scattering liquid crystal device shown in fig. 1, the liquid crystal composition containing a polymerizable compound selected from the group of compounds represented by general formula (1) as a first component, and containing a compound having negative dielectric anisotropy as a second component; a light-scattering liquid crystal device in which the liquid crystal composition is used; and a smart window in which the light-scattering liquid crystal device is used. This liquid crystal composition makes it possible to reduce the driving voltage as well as achieve exceptional transparency when no voltage is applied in a reverse-mode-type light-scattering liquid crystal device.
