Paper Abstract

The LC anchoring energy is related to the interaction of the Liquid Crystal molecules and alignment layer. Therefore the anchoring property of the Liquid Crystal in a display device could be tuned by controlling this interaction. To decrease the anchoring strength of the Liquid Crystals at the surface layer in display device, several kinds of perfluorinated additive were added to the Commercial Nematic Liquid Crystal, E7. The overall electro-optical and physical properties were measured to determine the role of the additive in Liquid Crystal mixtures. The molecular structure of the additive was changed to impose different polarity and interaction with the Liquid Crystal and alignment layer. The additives affected the surface property and produced a slippery surface without any phase separation.
