Abstract
ABSTRACT Ferroelectric copolymer of vinylide0ne fluoride and trifluoroethylene (70/30) was used as an alignment layer in nematic liquid crystal cells. The rubbed ferroelectric polymer films produce excellent planar orientation of liquid crystal molecules. We have found that the ferroelectric polymer film at one of LC cell surfaces results in strongly asymmetric electrooptical and electrical response. This fact was qualitatively explained by a model that assumes creating a “p-n” like junction between a liquid crystal and the ferroelectric polymer.
