A liquid crystal composition with high negative dielectric anisotropy, which is capable of exhibiting a high dynamic light scattering effect and of inducing similar characteristics into mixtures of the liquid crystal and another nematic liquid crystal and which derives an advantage from a larger mesomorphic temperature range, which comprises at least one compound of the formula: ##STR1## wherein R represents NO.sub.2, bromine or cyano; R.sub.1 is an alkyl or alkoxy group and R.sub.2 is an alkyl group.
一种具有高负电介质各向异性的液晶组合物,能够表现出高动态光散射效应,并且能够将类似特性诱导到液晶和另一种向列相液晶的混合物中,并从更大的介相温度范围中获得优势,其中至少包括下式的化合物:##STR1## 其中R代表NO.sub.2、溴或氰;R.sub.1是烷基或烷氧基,R.sub.2是烷基。
