摘要:
A liquid crystal composition comprising, as the essential components, trans-4-n-propyl-(4-ethylphenyl)-cyclohexane, trans-4-n-propyl-(4-cyanophenyl)-cyclohexane, trans-4-n-pentyl-(4-cyanophenyl)-cyclohexane, trans-4-n-pentyl-(4'-ethylbiphenyl-4)-cyclohexane and 4-(trans-4-n-pentylcyclohexyl)-4'-(trans-4-n-propylcyclohexyl)-biphenyl is drivable over a wide temperature range and can be operated rapidly at low temperatures.
