Abstract: The photo-induced alignment quality of a ferroelectric liquid crystals (FLC) onto a photochemical stable azodye film was studied for various procedures of the azodye film photo-treatment and the FLC structure. The alignment quality of FLC depends mainly on the order parameter of the azodye film, however the structure of FLC layer is also important. So, the photo-aligned deformed helix ferroelectric (DHF) liquid crystal exhibits the contrast ratio CR>500:1, while for the helix free FLC the contrast ratio CR>1500:1.
