摘要：
A novel liquid crystal compound having an intermediate group of a cis-1,4-substituted 2-butenyl group, low viscosity and a broad mesomorphic temperature range is provided, which compound is expressed by the following formula:
wherein R 1 represents an alkyl group of 1 to 10 carbon atoms; n represents 1 or 2, X represents a hydrogen atom, an alkyl group, a halogen atom, a cyano group, an alkoxy group, a methyl group substituted by 1 to 3 halogen atom(s) or a trihaloalkoxy group, Y and Y' each independently represents a hydrogen atom, a halogen atom.
