Zusammenfassung:	PURPOSE:To form the liquid crystal oriented film having good characteristics imparted with a desired orientation direction on a substrate by an LB method. CONSTITUTION:While the substrate 1 to be formed with the oriented film is held at plural points inclusive of one point at which a desired pulling up angle is obtainable by means of a holding jig, such as carrier 3, the substrate is transported continuously in a horizontal direction. The transmittance of the picture element parts of this substrate 1 is measured by an optical sensor 5. After the kind of the substrate is discriminated, the holding at the other points is released exclusive of holding at the one point at which the desired pulling up angle is obtd. in accordance with the result of the discrimination. The liquid crystal oriented film is cumulatively formed on the substrate by repeating the operation to perpendicularly immerse the substrate held at the one point in such a manner into a developed liquid 6 of a prescribed org. compd. then pulling up the substrate.
