Bistable Switching in Flc Cells Aligned by Photoanisotropic Films
Long-term perfect bistable snitching of 1,5 mu m thick Ferroelectric Liquid Crystal (FLC) cell oriented by photoanisotropic (PA) films was demonstrated even in case of a large spontaneous polarization 2 orientation Ps=100nC/cm(2). The condition of a good SmC* quality was shown to be the existence of a nematic phase N*. The bistability properties of PA-films aligned FLC cell, kept for a while in a short-curcuiting state, are easily restored, which is not observed in FLC cells oriented by usual rubbing technique.
