Abstract

PURPOSE:To weaken liquid crystal molecule control power by rubbing by rubbing a substrate in one direction, then rubbing the same in the direction opposite thereto by using a rubbing cloth having different fiber density. CONSTITUTION:Transparent electrodes 3, 4 consisting of ITO films and oriented films 5, 6 consisting of polyimide, etc., are successively formed on the transparent glass substrates 1, 2. The film 6 is then subjected to the rubbing treatment by the rubbing cloth (e.g.: rayon cloth) in one direction thereof and is subjected to the rubbing treatment in the direction opposite thereto by the cloth having the different fiber density. The substrate 2 subjected to the rubbing treatment and the untreated substrate 1 are thereafter stuck in such a manner that the films 5, 6 face each other, via a sealing resin 10. A ferroelectric liquid crystal 9 is sealed therein by which the liquid crystal cell is formed.
