<p>PURPOSE:To produce the oriented film for a liquid crystal at a low cost without requiring vacuum by moving a substrate having a resin layer while bringing an oscillating body having a piezoelectric reverse effect, i.e. electrostrictive effect into pressurized contact with the substrate. CONSTITUTION:The resin layer 4 having the resin layer 5 is disposed on a plate 6 which moves the substrate in an arrow direction (c) and while the tip of a head 2 is brought into pressurized contact with the substrate 4 at an angle (a), the plate 6 is moved under the oscillation applied thereto. Ruggedness is provided to the resin layer 5 on the substrate 4 by the extremely fine oscillation in this way. A suitable resin 3 or cloth may be used for the tip of the working head 2. The density, depth and shape of the surface of the resin film 5 can be controlled by the angle (a) between the oscillation direction (b) of the oscillating body and the substrate 4, the intensity of the oscillation and the oscillation frequency. The pressurized contact of the oscillation body by the magnetostrictive effect may be usable. The pretilt angle is increased in this way and the oriented film for the liquid crystal having the improved reproducibility is produced.</p> |
