Description

ABSTRACT:
A liquid crystal device is constituted by disposing a liquid crystal between a pair of substrates each having an electrode thereon and coated with an alignment film. The problem of hysteresis or reverse electric field effect of the liquid crystal device is alleviated by composing the alignment film with an alignment material, such as a polyimide, and a polymeric electroconductive compound, such as polyaniline. An electroconductive protective layer may be disposed between the electrode and the alignment film. The alignment film may be provided with an electroconductivity selectively at parts thereof above the electrode so as to provide an improvement in prevention of crosstalk between pixels.
