PROPERTY AND ELECTRO-OPTIC EFFECTS IN SPIN-COATED POLYMERIC FERROELECTRIC LIQUID CRYSTALS

Well-aligned thin films of polymeric ferroelectric liquid crystal have been prepared by means of a spin-coating method. Several types of electro-optical effects and the optical second-harmonic generation in these films have been measured. The characteristics of spin-coated polymeric ferroelectric liquid crystal film with a free surface have been discussed in comparison with those of conventional sandwich cells. The influences of the glass plates on the PFLC are also discussed.
