ABSTRACT:
A ferroelectric chiral smectic liquid crystal composition affording a high response speed and being cheap so that a high speed switching can be effected, which composition comprises at least one achiral smectic C compound and at least one chiral smectic C compound, characterized in that at least one of said at least one achiral smectic C compound contains at least two divalent six-memberd ring, directly linked by at least one single bond, at least one of said at least two divalent six-membered rings being selected from pyrimidin-2,5-diyl, pyridin-2,5-diyl, 1,4-phenylene or trans-1,4-cyclohexylene.
