Abstract
A liquid crystal device is constituted by a pair of substrates at least one of which is provided with an alignment control film, and a liquid crystal composition disposed between the substrates and contacting the alignment control film. The alignment control film comprises an amide polymer and a pyridine-based polymer. The liquid crystal device using a mixture alignment control film described above is effective in improving a switching characteristic by minimizing a depolarization field while keeping a uniform alignment characteristic.
