A mesomorphic compound represented by the following formula (I): ##STR1## wherein R.sub.1 and R.sub.2 respectively denote an alkyl group or alkoxy group each having 4-16 carbon atoms optionally substituted, halogen, --CN or --CF.sub.3. The mesomorphic compound is effective for providing a ferroelectric liquid crystal composition showing an improved low-temperature operation characteristic and a decreased temperature-dependence of response speed.
由以下公式(I)表示的一种中间向液晶化合物:##STR1##其中R.sub.1和R.sub.2分别表示具有4-16个碳原子的烷基基团或烷氧基团,可选择地取代,卤素,-CN或-CF.sub.3。该中间向化合物对于提供显示改进的低温操作特性和减少响应速度温度依赖性的铁电液晶组合物是有效的。
