According to the present invention, in the liquid crystal composition having a smectic C* phase, a liquid crystal compound having a fluoro-substituent and having a smectic C* is used to improve the reliability of the TFT-driven liquid crystal element and to achieve a low melting point. Thereby, the operating temperature of the liquid crystal element can be increased, and a liquid crystal composition which has not been conventionally provided can be provided.nThe liquid crystal composition of the present invention is characterized in that it does not contain a compound having a pyrimidine skeleton, and contains at least two liquid crystal compounds having two terminal groups of a mesogen group and a structure different from each other, and the liquid crystal original group has More than three ring structures, at least one of which is 2,3-difluorobenzene-1,4-diyl. |
