Patent ID: 7553521

Claim:
A liquid crystal display comprising a ferroelectric liquid crystal layer 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, a constituent material of a first photo alignment film out of the two photo alignment films is a photoreactive material which generates photoreaction to give anisotropy to the first photo alignment film, and a constituent of a second photo alignment film is an optically isomerizable material comprising an optically isomerization-reactive compound which generates an optical isomerization reaction to give anisotropy to the second photo alignment film; wherein the constituent material of the first photo alignment film has a different composition from the constituent material of the second photo alignment film; wherein a ferroelectric liquid crystal in the ferroelectric liquid crystal layer is a liquid crystal having no smectic A phase in a phase series thereof, exhibiting mono-stability and undergoing half V-shaped driving; and further wherein the ferroelectric liquid crystal forms mono-domain alignment in the ferroelectric liquid crystal layer.
