Abstract(in English) | We have studied the relationship between bent smectic layers of ferroelectric liquid crystal(FLC)stabilized by polymer fibers and molecular-alignment bistability, and realized the memory effect of the FLC by controlling the smectic layer structure. In forming the aligned polymer fibers with photopolymerization-induced phase separation, high pretilt alignment layers were used, so that the bending direction of FLC alignment was uniformed in cross-sectional plane. When the phase of FLC materials was changed from smectic A to smectic C^*, we applied ac voltage to the formed FLC/polymer composite film to stabilize cone axis of the FLC switching in rubbing direction. The bending of smectic layers in device plane was reduced, and the uniform layer structure allowed the memory effect of the device. The memory function accompanied the grayscale capability because of spatial distribution of bistable FLC domains with various threshold voltages. |
