摘要：

A zigzag defect-free surface-stabilized ferroelectric liquid crystal display (SSFLCD) has been fabricated using polyimide RN1199 (Nissan Chemical). The superiority of polyimide RN1199 in comparison with other conventional polyimide films is shown in terms of the observation of microscopic textures of aligned FLC and electrooptical bistability. From the results of characterization of polyimide films, such as the observation of surface morphology with an atomic force microscope (AFM) and the measurement of switching current, it is concluded that the formation of C2-uniform state may be attributed to the smooth surface of PI-RN1199 with a small pretilt angle this, in turn, results in excellent memory capability with high contrast ratio.
