Abstract

The stripe-shaped domain (SSD) structure has been obtained in the initial ferroelectric liquid crystal (FLC) alignment by doping phthalocyanine compound into the rubbed polyimide films. Atomic force microscopy (AFM) was used to investigate the aligning films and the corresponding aligning ability was evaluated through the pre-tilt angle measurement. The memory capability and the contrast ratio of the aligned SSFLC cells have been enhanced and improved with the appearance of the SSD structure. In addition, the stability of 64 × 80 electrically controlled FLC spatial light modulator has been improved, too. The possible formation mechanism of the SSD structure was also discussed.
