PROBLEM TO BE SOLVED: To provide an oriented film which is useful for a liquid crystal display and is prepared by irradiating linear polarizing ultraviolet light on a photosensitive compound, while inclining the oscillation surface of the electric field, and to provide a method for producing the same. SOLUTION: A photosensitive compound is coated on a substrate to form a film. The film is irradiated with linear polarizing ultraviolet light in an electric field vibration surface-inclined state by the use of a device comprising an ultraviolet light lamp, an electric source, and an optical element (for example, Glan-Teller prism) for converting natural light into polarized light, thus forming the film having an orientation-controlling force in a liquid crystal molecule- twisting direction. Consequently, the liquid crystal-orienting film effective for a liquid crystal display can be provided, because the defect of the orientation can sufficiently be controlled, even when the size of a pre-tilt angle is insufficient and even when the strength of an anchor ring is small, although the pre-tilt angle is large. |
