摘要:
The present invention intends to provide a novel cyclohexane compound that can form a liquid crystal composition of which response speed is improved when mixed with a nematic liquid crystal and the like and to provide a specified liquid crystal composition in which a novel cyclohexane compound is mixed. The novel cyclohexane compound is represented by the following formula (1).
(In the formula (1), R 1 and R 2 represent the same or different R, ROCO or RCOO, and the R represents an alkyl group. The alkyl group may have an unsaturated bond, and, in the group, -CH 2 - may be substituted with -O-, -CO- or -COO-, and a part of or an entirety of hydrogen atoms may be substituted with a halogen atom or a cyano group. X and Y each independently represents a halogen atom or a hydrogen atom and does not simultaneously represent a hydrogen atom. Further, alternatively, X represents an oxygen atom and Y represents a direct bond to the oxygen atom.)
