FERROELECTRIC LIQUID CRYSTAL OPTICAL DEVICES

摘要

FERROELECTRIC LIQUID CRYSTAL OPTICAL DEVICES Excellent ordering in ferroelectric liquid crystal devices is obtained by utilizing a material having a smectic C phase and no higher temperature orthogonal smectic phases. Ordering is accomplished by the combination of 1) contacting the liquid crystal material in the smectic C phase with an ordering substance and 2) subjecting the liquid crystal material to a slowly varying electric field.
