Title:
OPTICALLY ISOTROPIC LIQUID CRYSTAL MEDIUM AND OPTICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/065622
Kind Code:
A1
Abstract:
Provided is a liquid crystal medium having stability to heat, light, and the like, a broad liquid crystal phase temperature range, large refractive index anisotropy, and large dielectric constant anisotropy, and having an optically isotropic liquid crystal phase. A liquid crystal composition characterized in containing: an achiral component (T), containing at least one compound selected from a group of compounds represented by formula (1), as a first component; and a chiral agent, and manifesting an optically isotropic liquid crystal phase. (1) Herein, for example, R1 is an alkyl having 1-20 carbon atoms, rings A1-A6 are 1,4-phenylene, Z1-Z7 are single bonds, Y1 and Y2 are fluorine, X1 is a halogen, and i, j, k, m, n, p, and q are each independently 0 or 1.
