| titleOfInvention | Liquid crystal composition |
| abstract | The present invention relates to a liquid crystal composition for use in thermal writing type liquid crystal displays in which a thermooptical effect is utilized. A technical subject of the present invention is to provide a liquid crystal composition characteristically having an extremely narrow nematic range and a low-melting phase transition point, and another object of the present case is to provide a liquid crystal display element using this composition. n The present invention is directed to a liquid crystal composition which comprises a component A comprising at least one of 4-n-alkyl-4'-cyanobiphenyls represented by the formula (1) ##STR1## wherein R 1 is an alkyl group having 8, 9, 10, 11 or 12 carbon atoms, and a component B comprising at least one of 4-n-alkoxycarbonyloxy-4'-cyanobiphenyls represented by the formula (2) ##STR2## wherein R 2 is an alkyl group having 8, 9, 10, 11 or 12 carbon atoms, a ratio of the component A to the component B being from 25:75 to 95:5. n Since the liquid crystal composition of the present invention has a nematic range of 2° C. or less, the writing velocity of the display element is accelerated, and the contrast on a projection screen is bettered, whereby display quality is improved remarkably. Additionally, since having a melting point of 0° C. or less, the liquid crystal composition of the present inventin can be used in thermal writing type liquid crystal displays without any problems which can be utilized indoors and at room temperature. |
