Liquid crystal device |
| abstract |
A liquid crystal device is constituted by a pair of transparent substrates each having thereon a transparent electrode, and a chiral smectic liquid crystal composition lacking cholesteric phase disposed between the substrates so as to assume at least two optically stable states. At least one of the substrates is provided with an alignment film which comprises a polyimide represented by a recurring unit of formula (I) shown below and has been subjected to a uniaxial aligning treatment. ##STR1## wherein A denotes a tetravalent aliphatic hydrocarbon group free from a planar structure or a tetravalent alicyclic hydrocarbon group, and n is an integer of at least 1. The chiral smectic liquid crystal composition may preferably contain at least one species of fluorine-containing mesomorphic compound comprising a fluorocarbon terminal portion and a hydrocarbon terminal portion connected with a central core and having a smectic phase or a latent smectic phase. |
