Abstract:
A liquid crystal device, comprising:a pair of substrates each having thereon an electrode and a composite alignment film comprising a polymeric component for homeotropically aligning a liquid crystal and a polymeric component for homogenously aligning a liquid crystal, anda fluorine-containing nematic liquid crystal disposed between the substrates, whereinsaid composite alignment film aligns liquid crystal molecules of the nematic liquid crystal in a bend alignment state without any voltage application and provides a retardation R (nm) of the liquid crystal device under application of a prescribed voltage relative to a refractive index anisotropy .DELTA.n of the liquid crystal and a cell thickness d (nm) of the liquid crystal device, providing a retardation factor R/.DELTA.n.multidot.d of at most 0.3.
