OPTICALLY ISOTROPIC LIQUID CRYSTALLINE MEDIUM, AND OPTICAL ELEMENT |
| 摘要 |
A liquid crystal medium having a wide temperature range of a liquid crystal phase, a large optical anisotropy, and a large dielectric anisotropy and having an optically isotropic liquid crystal phase is provided. The liquid crystal medium is characterized by containing a liquid crystal compound having a pyrimidine ring and a linking group -CF 2 O- and a chiral dopant, and exhibiting an optically isotropic liquid crystal phase. |
