PURPOSE:To attain high-speed response and bistable operation with the large- area element by laminating org. monomolecular films consisting of a mixture composed of specified polyamic acid and specified org. material to >=1 layers and removing part thereof to form ruggedness, then laminating a ferroelectrtic liquid crystal thereon. CONSTITUTION:At least >=1 layers of the monomolecular films 3, 6 which are developed on a water surface, have photosensitivity and consist of the org. material constituted of the amide acid expressed by formula I and the pyridine org. matter expressed by formula II are laminated on substrates 2, 5 and are partly removed to form the ruggedness and thereafter, the ferroelectric liquid crystal 4 is formed thereon. The easy change of the number of laminations and change of the pitches of the ruggedness are, therefore, possible even if the solid state properties of the liquid crystal vary and the orientation conditions vary. The surface condition meeting the orienting conditions of the liquid crystal material used is easily obtd. in this way and since the uniform films can be formed, the liquid crystal element having good orientational property is obtd. The excellent optical response characteristic is consequently obtd. and the correspondence of the bistable operation to the large area is possible. |
