| titleOfInvention | Liquid crystal composition containing a cyanobiphenyl and a phenyl benzoate |
| abstract | A liquid crystal material suitable for a multiplexed twisted nematic device comprises a mixture of: (a) one or more cyanobiphenyl compounds having a formula: <IMAGE> where R1 is an n-alkyl group containing between 7 and 12 carbon atoms inclusive, and (b) one or more benzoate esters having a formula: <IMAGE> where R2 is an n-alkyl group containing 3, 5 or 7 carbon atoms and R3 is an n-alkyl group containing 5, 7 or 9 carbon atoms, the mixture containing between 53 and 90 per cent (inclusive) by weight of the compound(s) of formula (II). Preferably the mixture contains between 60 and 80 per cent by weight of the compound(s) of formula (II). The mixture may be further mixed with other compounds, eg other 4-n-alkyl- or -alkoxycyanobiphenyls or esters, eg having five or less carbon atoms in their n-alkyl group, the compound(s) of formula (II) being present as the major overall biphenyl constituent(s), or high clearing point nematics, ie materials with nematic-to-isotropic liquid (N-I) transition temperatures at over 150 DEG C. |
