Abstract:
1. A liquid crystal display comprising a ferroelectric liquid crystal layer sandwiched between two substrates, wherein an electrode and a photo alignment layer are each successively formed on opposite faces of the two substrates facing each other; wherein a constituent material of each photo alignment layer is a photo-isomerizable material comprising a photo-isomerization-reactive compound which generates a photo-isomerization reaction to give anisotropy to the respective photo alignment layer, and the constituent material of the respective photo alignment layers have a different composition from each other, 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.
