ABSTRACT:
A ferroelectric liquid crystal device is constituted by a pair of substrates each having thereon an electrode and an alignment film, and a ferroelectric liquid crystal disposed between the substrates. The alignment film on at least one substrate comprises laminated layers of at least two species of electroconductive polymers having mutually different optical band gaps Eq.sup.opt. The ferroelectric liquid crystal device can effectively remove undesirable reverse electric field effect even when a liquid crystal having a large spontaneous polarization is used, and exhibits little change in threshold characteristic with time.
