| titleOfInvention | Liquid crystal composition |
| abstract | A liquid crystal compositon for use in thermal writing type liquid crystal display utilizing a thermo-optical effect and a liquid crystal display element using same are disclosed. The liquid crystal composition has an extremely narrow nematic range and a phase transition of a low melting point. The liquid crystal composition contains as major components, component A composed of 4-n-octyl-4'-cyanobiphenyl, 4-n-dodecyl-4'-cyanobiphenyl and at least one 4-n-alkyl-4'-cyano biphenyl represented by general formula (I) (wherein R' represents an alkyl group having 9, 10 or 11 carbon atoms) and component B composed of at least one 4-n-alkanoyloxy-4'-cyanobiphenyl represented by general formula (II) (wherein R 2 represents an alkyl group having 8 or 9 carbon atoms) and at least one 4-n-alkanoyloxy-4'-cyanobiphenyl representedn n by general formula (III) (wherein R 3 represents an alkyl group having 10, 11 or 12 carbon atoms), with the ratio of compo- nentAto component B being 95:5to 45:55. The composition may optionally further contain at least one 4-n-alkoxy-4'-cyanobiphenyl represented by general formula (IV) (wherein R 4 represents an alkyl group having 8 to 12 carbon atoms). The liquid crystal composition serves to accelerate the writing speed of the display element and improve the contrast of projected images, thus markedly improving display quality. Since the melting point is not higher than 0°C, the composition does not cause any problem when used in thermal writing type liquid crystal display to be used in a room at room temperature. |
