| titleOfInvention | Liquid crystal composition |
| abstract | The present invention relates to a liquid crystal composition used for thermal writing type liquid crystal display devices utilizing a thermooptical effect, and a liquid crystal display element using the composition. n The object of the present invention is to provide a liquid crystal composition having an extremely narrow nematic range and a low-melting phase transition point, and also to provide a liquid crystal display element using the composition. n The present invention is directed to a liquid crystal composition mainly comprising a component A comprising 4-n-octyl-4'-cyanobiphenyl, 4-n-dodecyl-4'-cyanobiphenyl and at least one member of 4-n-alkyl-4'-cyanobiphenyls represented by the formula (I), ##STR1## wherein R 1 is an alkyl group of 9, 10 or 11 carbon atoms, and a component B comprising at least one member of 4-n-alkanolyloxy-4'-cyanobiphenyls represented by the formula (II) ##STR2## wherein R 2 is an alkyl group of 8 or 9 carbon atoms, and at least one member of 4-n-alkanoyloxy-4'-cyanobiphenyls represented by the formula (III) ##STR3## wherein R 3 is an alkyl group of 10, 11 or 12 carbon atoms, the ratio of the component A to the component B being in the range of 95:5 to 45:55. n The liquid crystals composition may further comprise at least one member of 4-n-alkoxy-4'-cyanobiphenyls represented by the formula (IV) ##STR4## wherein R 4 is an alkyl group of 8 to 12 carbon atoms. |
