ABSTRACT:
A bistable ferroelectric liquid crystal display device is provided. The device comprises a first substrate, a second substrate opposed to said first substrate, said substrates disposed to provide a non-helicoidal alignment of the ferroelectric liquid crystal material and electrodes on said substrates to define one or a plurality of pixels, said electrode bearing first substrate having an aliphatic polyamide or polyester alignment coating thereon and said electrode bearing second substrate having an organosilsesquioxane polymer coating thereon, and a ferroelectric liquid crystal mixture comprising compounds having fluorinated tail portions with multiple CF.sub.2 groups disposed between said substrates with the proviso that at least one of said substrates is transparent. Also provided is a method for providing an aligned ferroelectric liquid crystal display device.
