Surface Alignment of Ferroelectric Liquid-Crystals Using Side-Chain Ferroelectric Liquid-Crystal Polymer
New surface alignment material for surface stablized ferroelectric liquid crystal displays (SSFLCDs) is investigated. Side chain ferroelectric liquid crystal polymer (SCFLCP) such as Poly{methyl 4-[[[S-(-)-2-methyl-1-butoxy]carbonyl] phenyl]4’-hexyloxybenzoyl} Siloxane was used as the alignment layer which resulted in good uniform alignment of FLC molecules without zig-zag defects. However, RN-715 polyimide alignment layer showed random alignments with some zig-zag defects in the SSFLC cells. After the field stablization of (+/-)20 V AC, the typical stripe-shaped patterns appeared. Good electro-optical performance was observed by using SCFLCP.
