ABSTRACT:
The invention provides a liquid crystal displays using a ferroelectric liquid crystal, which can give mono-domain alignment of ferroelectrical liquid crystal without forming orientation defects 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 provides liquid crystal displays comprising a ferroelectric liquid crystal sandwiched between two substrates, wherein an electrode and a photo alignment film are each successively formed, the first of which is a photoreactive material which generates photoreaction to give anisotropy to the photo alignment film, and the constituent material of the second film is an optically isomerizable material comprising an optically isomerization-reactive compound.
