摘要：
A novel liquid crystal compound exhibiting SC phase which, when added to an optically active liquid crystal, makes the resulting chiral smectic liquid crystal material exhibit superior performances in liquid crystal display elements utilizing the ferroelectricity of the material, and a chiral smectic C composition using the compound, which compound is expressed by the formula ##STR1## wherein R.sup.1 l represents an alkyl group of 7 to 12 carbon atoms and R.sup.2 represents an alkyl group of 5 to 12 carbon atoms.
