— A direct‐multiplexed ferroelectric liquid‐crystal display, having a contrast ratio as high as 35:1 without showing zigzag defects, has been realized by using an electrical conductive orientation polymer: a polypyrrole film together with a special material containing naphthalene‐based ferroelectric liquid crystals. The polypyrrole orientation films can effectively suppress the formation of depolarization fields, resulting in a stable memory capability and a high contrast ratio.
