ABSTRACT:
Liquid crystal compositions including as the main component at least one P, P'-dialkylazoxyhenzene selected from Compounds (1) of the general formula: ##STR1## wherein R.sub.1 represents a straight-chain alkyl group of 1-10 carbon atoms, and R.sub.2 represents a straight-chain alkyl group of 1-10 carbon atoms and at least one component selected from Compounds (2), Compounds (3) and Compounds (4) of the general formulae, respectively: ##STR2## wherein R.sub.3 represents a straight-chain alkyl or straight-chain alkoxy group of 1-10 carbon atoms, R.sub.4 represents a straight-chain alkyl or straight-chain alkoxy group of 1-10 carbon atoms, R.sub.5 represents a straight-chain alkyl group of 1-8 carbon atoms, R.sub.6 represents a straight-chain alkyl group of 1-8 carbon atoms, and R.sub.7 represents a straight-chain alkyl group of 1-10 carbon atoms and R.sub.8 represents a straight-chain alkyl group of 1-10 carbon atoms. These liquid crystal compositions are suitable for multiplex drive.
