摘要:
A liquid crystal device, particularly a ferroelectric liquid crystal device, is constituted by disposing a liquid crystal disposed between a pair of rubbing-treated substrates. The uniaxial alignment control force exerted by rubbing is gradually weakened as the rubbing treatment is successively applied to a large number of substrates. This is compensated by varying a rubbing condition, such as a relative moving speed, a rotational speed, or a pressing depth against the substrate of a rubbing roller. Alternatively, such a change in uniaxial alignment control force with time may be utilized for compensating for a difference in uniaxial alignment control force attributable to a difference in stripe electrode extension relative to the rubbing direction.
