Title:
LIQUID CRYSTAL COMPOSITE AND LIQUID CRYSTAL LIGHT CONTROL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/026621
Kind Code:
A1
Abstract:
Provided are: a liquid crystal composite that is suitable for light control and contains a liquid crystal composition that satisfies at least one of characteristics such as a high upper limit temperature, low lower limit temperature, low viscosity, large optical anisotropy, and large positive dielectric anisotropy or exhibits an adequate balance among at least two of these characteristics; and a liquid crystal light control element containing the liquid crystal composite. This liquid crystal composite contains a liquid crystal composition containing a polymer and a specific compound having large positive dielectric anisotropy. The liquid crystal composite may further contain a specific compound having a high upper limit temperature or low lower limit temperature, and a specific compound having large negative dielectric anisotropy.
