We investigated the electrooptical properties of vertically aligned ferroelectric liquid crystal (VAFLC) cells by applying a transverse electric field induced by interdigital electrodes. Compared with a surface-stabilized FLC (SSFLC) cell, a VAFLC cell has an analog-grey scale capability requiring a high driving voltage. In this study, we propose two alignment methods, the single- and double-sided rubbed methods, to reduce the driving voltage of the VAFLC cell. The dynamic response time is below 1 ms in our methods. A single-sided polyimide aligned method can achieve a contrast ratio of 520 at an applied voltage of 50 V.
