ABSTRACT:
The step of putting drops of liquid crystal onto a substrate includes the putting of drops of liquid crystal onto the substrate at spaced intervals of 15 mm or less. Thus, an impurity concentration is made equal to or less than 30 ppm in a region in which the liquid crystals collide with each other when the bonding of the substrates causes diffusion of the liquid crystals through a liquid crystal cell. A liquid crystal dripping apparatus including a branch nozzle having a plurality of discharge openings is used in the step of putting drops of liquid crystal onto the substrate. By a single dispensing operation, the apparatus simultaneously puts drops of liquid crystal onto a plurality of spots on the substrate.
