ABSTRACT:
A liquid crystal device utilizing a stably retained bookshelf structure is constituted by disposing a ferroelectric liquid crystal layer between a pair of substrates. The ferroelectric liquid crystal layer includes a first liquid crystal region in a first uniform state wherein liquid crystal molecules assume one stable state, a second liquid crystal region in a second uniform state wherein, liquid crystal molecules assume another stable state, and a third liquid crystal region in a twist state disposed between the first and second liquid crystal regions. Liquid crystal molecules at both substrate boundaries are controlled to have mutually opposite pre-tilt directions, and a disclination is formed between the first and second liquid crystal regions.
