| 摘要 |
The present invention provides a non-conventional liquid crystal composition which exhibits a smectic C* phase, in which a liquid crystal compound having a fluorine substituent introduced thereinto and exhibiting smectic C* is used to improve the reliability in a TFT-driven liquid crystal element and decrease the melting point of the liquid crystal composition, thereby expanding the working temperature range of the liquid crystal element. The liquid crystal composition according to the present invention is characterized in that a compound having a pyrimidine backbone is not contained and at least two liquid crystal compounds each having at least three ring structures are contained, wherein at least one of the ring structures has a mesogenic group that is a 2,3-difluorobenzen-1,4-diyl group and also has two terminal groups having different structures from each other. |
