PURPOSE:To obtain a uniform and defectless oriented film by mixing the amphipathic high-polymer material expressed by the prescribed formula and >=1 kinds of low-molecular materials at an arbitrary ratio and laminating >=1 layers of mixed monomolecular films developed on a water surface on a substrate formed with an electrode layer, then subjecting the films to a heat treatment to effect a ring closing reaction, thereby forming the oriented film. CONSTITUTION:The amphipathic high-polymer material having the repeating units expressed by the formula I, the formula II and having 2,000 to 300,000 average mol. wt. and at least >=1 kinds of the low-molecular materials are mixed at an arbitrary ratio. The mixed monomolecular films obtd. by developing on the water surface are laminated in >=1 layers on the substrate formed with the electrode layer and are subjected to such a heat treatment as to induce the ring closing reaction, by which the liquid crystal element including the thin films formed in such a manner is obtd. In the formula I, R1, R2, R3, R4, R5, and R6 are as shown in explanations and in the formula II, R1, R2, R3, and R4 are the same as the above-mentioned explanations. |
