Abstract
A method is provided of discharging liquid drops of an alignment film from a corresponding plurality of nozzles arranged with a predetermined interval in the direction Y that crosses a scanning direction X by scanning a liquid drop discharge head having the plurality of nozzles in the scanning direction. The liquid drops of the alignment film are discharged to a coated area to be coated with the alignment film by scanning the liquid drop discharge head once. The coated area corresponds to the entire display panel of a single panel or the entire area in which the alignment film is to be formed in a single chip.
