Abstract

Ferroelectric liquid crystalline polymers (FLCP) were synthesized. These ferroelectricities were confirmed directly by measuring the polarization reversal currents and other electro- optical properties. The smectic layer structure of FLCP was also studied. A chevron structure similar to that of low molecular weight FLC was observed even in the FLCP cell. But the zigzag defects were not so sharp, which means it is easy to get a good orientation even in large area displays. We succeeded in making a FLCP display of 15 cm X 40 cm without any alignment layers.
