It is known that two easy axes are generated by one direction rubbing on special alignment film which is consisting of polyamide mixed with polyvinylcinnamat (PVCi), both of which are horizontal alignment materials. A bi-stable switching cell with a nematic LC was fabricated by using this special alignment film. Switching between bi-stable orientation states was tried by operating the flexo polarization. For the flexo polarization, a hybrid orientation structure was used as a sample cell, so vertical alignment film was used for the other side of the surface substrate. An interdigit electrode, for applying an electric field in the plane, was formed on one side of the substrate surface. It was confirmed that switching to the other orientation state depended on the polarity of the applied electric field. However, long-time memory properties were not observed, so it seemed that the azimuthal anchoring energy is not strong enough to keep each orientation state.
