A colorless liquid crystalline compound having at least one 6-membered ring and non-cyclic end groups in the molecular skelton, said 6-membered containing two or more carbon atoms, at least one of which is directly bonded to a methylene group of a non-cyclic group having an alkoxy group at another end has a wide mesomorphic range. When said colorless liquid crystalline compound is mixed with a liquid crystal composition, the resulting mixture also has an enlarge mesomorphic range and in almost all cases has a reduced viscosity.
