Abstract:
1. A producing method for a liquid crystal display comprising steps of: forming photo alignment layers on two substrates where electrodes are formed, by using photo alignment layer materials having different compositions for each photo alignment layer, wherein a constituent material of the respective photo alignment layer is a photo-isomerizable material or a photoreactive material which generates a photoreaction to give anisotropy to the photo alignment layer; sticking the two substrates onto each other so as to make the photo alignment layers formed on the substrates face each other; injecting between the photo alignment layers a ferroelectric liquid crystal, wherein the ferroelectric liquid crystal has no smectic A phase in a phase series thereof, exhibits mono-stability and undergoes half-V-shaped driving; and forming a liquid crystal layer without using an electric field induced technique, wherein the ferroelectric liquid crystal is aligned by slow cooling, and further wherein the ferroelectric liquid crystal forms mono-domain alignment.
