Liquid crystal device with phenylenevinylene or phenylene sulfide alignment films having particular high electrical conductivity

A display system, comprising:

• a liquid crystal device comprising a pair of opposing substrates and a liquid crystal rendering a chiral smectic phase disposed between said pair of substrates;
• and
• communication synchronizing means for generating image information and transferring said image information to said liquid crystal device,
• wherein at least one of said substrates is provided with an alignment film that exhibits an electrical conductivity of greater than 10.sup.-8 .OMEGA..sup.-1 cm.sup.-1, said alignment film comprising a polymer having a phenylenevinylene or phenylene sulfide skeleton;
• and
• wherein an insulating layer comprising a material selected from the group consisting of SiO.sub.2, TiO.sub.2 and Ta.sub.2 O.sub.5 is provided between said substrate and said alignment film.

A display method, comprising the steps of:

• selecting a liquid crystal device comprising a pair of opposing substrates and a liquid crystal rendering a chiral smectic phase disposed between said pair of substrates, wherein at least one of said substrates is provided with an alignment film that exhibits an electrical conductivity of at least 10.sup.-8 .OMEGA..sup.-1 cm.sup.-1 ;
• said alignment film comprising a polymer having a phenylenevinylene or phenylene sulfide skeleton;
• and
• displaying information by driving said liquid crystal.
