Abstract
Liquid crystal compounds which are para-substituted phenyl esters of para-substituted cyclohexyl carboxylic acid, are effective in compositions for use in liquid crystal display devices, particularly for operation in the multiplexing mode. The cyanophenyl esters may be used in a wide variety of compositions. The compounds are stable, inert to moisture, light and oxygen and have low viscosity. Moreover, they can be used in compositions using the guest-host effect.
