Abstract
PURPOSE: To make the pretilt angle of liquid crystal molecules close to 0° and obviate the occurrence of reverse tilt at the voltage application by evaporating an orientation treatment material onto the substrate surfaces from specific two directions simultaneously or repeatedly alternately.
CONSTITUTION: Substrates 43 of liquid crystal cells with their orientation treatment sides being faced outside are mounted to a rotator 42 which rotates about a rotating axis 14. A mask plate 44 which defines the angle of vapor deposition is provided between a vapor source 47 which produces vapor currents 48 and the rotator 42. This plate 44 is formed with a first vapor deposition hole 45 being in the direction inclined 80° from the normal of the substrate 43 and a second vapor deposition hole 46 being in the normal direction. Out of the vapor currents 48, only those which have passed through the holes 45, 46 deposit on the substrates 43 at the vapor deposition angle within a fixed range. As the rotator 42 rotates, the first and second vapor depositions take place alternately. Thereby, the repetitive stability of orientation characteristics in volume production is improved
