(57) [Summary] [Structure] Formula: Wherein R 1 represents a linear alkyl group having 7 to 10 carbon atoms, R 2 represents an alkyl group having 1 to 8 carbon atoms, and n is 1, 2 or A compound represented by 3) and a liquid crystal mixture comprising at least one component of which the compound is at least one component. The compound of the present invention gives a relatively wide smectic mesophase having a low melting point and a low viscosity, and a mixture with a known liquid crystal basic component suppresses the crystallization of individual components, resulting in a relatively wide mesophase. It gives a phase and excellent low temperature behaviour. |
