| 摘要 |
A main object of the invention is to provide liquid crystal displays using a ferroelectric liquid crystal, which can give mono-domain alignment of the ferroelectric liquid crystal without forming orientation defects such as zigzag defects, hairpin defects and double domains and which is so remarkably good in orientation stability that the orientation thereof can be maintained even if the temperature of the liquid crystal is raised to the phase transition point or higher. The invention attains the object by providing liquid crystal displays comprising a ferroelectric liquid crystal sandwiched between two substrates, wherein an electrode and a photo alignment film are each successively formed on inner sides of the substrates facing each other, the constituent material of the first orientation film out of the two photo alignment films is a photoreactive material which generates photoreaction to give anisotropy to the photo alignment film, and the constituent material of the second photo alignment film is an optically isomerizable material comprising an optically isomerization-reactive compound which generates optical isomerization reaction to give anisotropy to the photo alignment film.
