A liquid crystal display device using a ferroelectric liquid crystal in which mono-domain alignment of the ferroelectric liquid crystal is achieved without causing zigzag defects, hairpin defects, and alignment defects such as double-domain, this alignment can be maintained even if the temperature exceeds the phase- transition point, and the alignment stability is excellent. The liquid crystal display device comprising two substrates and a ferroelectric liquid crystal interposed between them is characterized in that on the opposed surfaces of the substrates, electrodes and optical alignment films are sequentially provided, the optical alignment films are made of photoreactive materials imparting anisotropy to the optical alignment films by causing photoreaction, and the photoreactive materials of the optical alignment films have mutually different compositions. ® KIPO & WIPO 2007 |
