摘要：

We demonstrate that ferroelectric liquid crystals are suitable for application in polymer-dispersed liquid crystal (PDLC) displays. The alignment of the liquid crystal can be controlled by mechanical shear during the polymerization-induced phase separation between the liquid crystal and the UV-curable adhesive which forms the polymer matrix. Helical unwinding in the smectic SmC* phase and the electroclinic effect in the smectic SmA phase have been found in these samples. Both effects lead to a rotation of the optical axis in the plane perpendicular to the electric field. Switching times are of the order 100-mu-s.
