Abstract

PURPOSE:To produce the oriented film for liquid crystal molecules having high reproducibility and reliability at a low cost by irradiating a substrate having a resin layer on the main surface with collimated beams of UV light at a prescribed angle with the substrate. CONSTITUTION:Certain microorder is needed at about the molecular level on the surface of the oriented film at the boundary of a device wall in order to orient the liquid crystal molecules and this order is the case in which the groups interacting with the liquid crystal molecules are regularly arrayed or the recessed and projecting shapes are regular. The orientation control power is eventually considered to be imposed on the liquid crystal molecules by a decrease in the free energy by a volume expelling effect. The substrate 4 having the resin layer 3 is, thereupon, irradiated with the collimated beams of the UV light at the prescribed angle alpha. Ruggedness is effectively provided to the resin layer 3 on the substrate 4 by creating the fine spacial distributions of the collimated beams of the UV light in such a manner, by which the liquid crystals are effectively oriented. A mask is used in tight contact with the resin layer 3 and the resin layer is thereafter rubbed to obtain the better effect. The high pretilt orientation is thereby obtd.
