Patent ID: 7553524

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 opposite faces of the two substrates facing each other; wherein a constituent material of the respective photo alignment layer is a photoreactive material which generates a photoreaction to give an isotropy to the photo alignment layer, the photoreaction of the constituent material of one respective photo alignment layer being a photo-dimerization reaction; and the constituent material of the respective photo alignment layer has a different composition from each other with the ferroelectric liquid crystal layer sandwiched therebetween; and 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.
