<p>PURPOSE:To obtain the pretilt angle of about 2 times the pretilt angle obtainable with a rubbing method and to improve the display characteristics of a liquid crystal display device by disposing acicular magnetic materials and oriented films for liquid crystals in proximity to each other, controlling the contact state of the acicular magnetic materials and the resin surfaces by a magnetic field, thereby changing the resin surfaces. CONSTITUTION:A polyimide resin and polyamic resin which are adjusted in viscosity by using a solvent are spin-coated on two sheets of respectively separate glass substrates 5. The substrates with the resins faced on the front are imposed respectively separately on a moving table 4 and the resin layers are subjected to an orientation treatment. The acicular magnetic materials are provided in proximity to the resin surfaces and the pretilt angle is generated in the resins by the magnetic field thereof in order to execute the orientation treatment. A rayon film 2 contg. magnetic powder 3 is previously wound on the surface of an aluminum pipe 1 and while this pipe is rotated, the resin layers are rubbed by the tips of the acicular magnetic powder, by which the desired orientation is executed.</p> |
