We report on the requirements of Ferroelectric Liquid Crystal Displays (FLCDs) for Smart Card applications and on the switching behaviour of FLCs with different spontaneous polarization. Furthermore a flexographic printing technique of FLCs on plastic substrates is presented. Experiments show that the phase of the FLC during the printing process has a big influence on the switching voltage of the FLCD. After printing the FLC the substrates are laminated to a display. This technique allows a vacuum free and in consequence economic mass production process of bistable FLC-Displays on flexible plastic substrates.
