Abstract

PURPOSE: A liquid crystal composition that contains a specific aromatic compound whereby the dielectric field anisotropy is small in high-frequency zone and large in low-frequency zone, permits two-wave dynamic driving, being useful as digital display for table calculator and watch.
CONSTITUTION: The objective composition contains compounds of formula I (R, R' are 1W8C straight chain alkyl). For example, compounds of formula II, III and IV are mixed to give the objective composition.
USE: The resulting composition is suitably used as character display since the driving voltage is low.
