ABSTRACT:
An object of the invention is to provide a liquid crystal device that uses a smectic liquid crystal and that can produce a uniform display. The liquid crystal device includes a pair of substrates, a smectic liquid crystal provided between the pair of substrates, an injection hole for injecting therethrough the smectic liquid crystal into a gap formed between the pair of substrates, a plurality of scanning electrodes arranged at right angles to the direction of injection of the smectic liquid crystal between the pair of substrates, an alignment film deposited over the plurality of scanning electrodes, and voltage applying means for applying a voltage to the plurality of scanning electrodes in sequence proceeding from a side nearest to the injection hole toward a side farthest therefrom.
