摘要
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.
