<p>A liquid crystal device comprises a pair of substrates and a ferroelectric liquid crystal disposed between the substrates. At least one of the pair of substrates has an alignment control film formed of an aliphatic polyimide resin having a function of aligning said plurality of layers preferentially in one direction. The aliphatic polyimide resin film stably provides a uniform alignment state with a large tilt angle than a conventional alignment control film of polyimide or polyvinyl alcohol over a long period. The liquid crystal device also provides a color tone of black in its darkest state.</p> |
