    • An anti-ferroelectric liquid crystal composition containing a phenyl triester compound of the formula (1), wherein R1 is a linear alkyl group having 6 to 12 carbon atoms, m is an integer of 0 to 3, n is an integer of 1 to 3, and X1 is a hydrogen atom or a fluorine atom, and an anti-ferroelectric liquid crystal compound of the formula (2),  wherein R2 is a linear alkyl group having 6 to 12 carbon atoms, X2 is a hydrogen atom or a fluorine atom, A is —CH3 or —CF3, r is 0 or 1 and C* is an asymmetric carbon, provided that when A is —CH3, r is 0 and p is an integer of 4 to 10, that when A is —CF3 and when r is 0, p is an integer of 6 to 8, and further than when A is —CF3 and when r is 1, q is an integer of 5 to 8 and p is 2 or 4. The phenyl triester compound and anti-ferroelectric liquid crystal compound composition is not only improved in response speed but also shows remarkably controlled layer rotation, and it can achieve a simple matrix liquid crystal display device which is free of a change in contrast and is highly reliable in use for a long period of time.
    • 一种含有式(1)的苯基三酯化合物的反铁电液晶组合物,其中,R 1为碳原子数6〜12的直链烷基,m为0〜3的整数,n为1〜3的整数。 ,X 1为氢原子或氟原子,式(2)的反铁电液晶化合物,其中,R2为碳原子数6〜12的直链烷基,X2为氢原子或氟原子 A为-CH 3或-CF 3,r为0或1,C *为不对称碳,条件是当A为-CH 3时,r为0,p为4至10的整数,当A为-CF 3和 当r为0时,p为6至8的整数,并且当A为-CF 3时,当r为1时,q为5至8的整数,p为2或4.苯基三酯化合物和抗 - 铁电液晶化合物组合物不仅提高了响应速度,而且显示出显着控制的层旋转,并且可以实现简单的矩阵液晶显示装置,其不含ch 相比之下,在长时间使用中是高度可靠的。
