<p>PURPOSE:To control a liquid crystal molecule pretilt angle by exposing a photosensitive resin film corresponding to the intensity of light by interference fringes, and adjusting the intervals of the interference fringes and controlling the orientation of a liquid crystal molecule oriented film. CONSTITUTION:Laser light is split by a beam splitter 5 in two directions and a substrate 1 is irradiated with the split laser light beams by mirrors 6 and 7 at specific angles theta1 and theta2 of incidence. Spatial filters 12 and 13 consisting of lenses 8 and 9 and pinholes 10 and 11 convert the laser light beams into divergent spherical waves. The interference fringes are formed on the substrate with the mutually coherent spherical waves and a photosensitive resin film 2 which is exposed corresponding to the intensity of light by the interference fringes is developed to form grooves on the substrate 1 in a since wave shape corresponding to the intensity of the interference fringes, thus forming the liquid crystal molecule oriented film. The interference fringes are constituted properly to form grooves in various shapes in the photosensitive resin film, and consequently the liquid crystal molecule pretilt angle can be controlled.</p> |
