Abstract

Conventionally, while performing a conventional liquid crystal dropping and bonding, an adjustment to make one drop correspond to a desired amount is carried out in a preliminary setup of production, because the feed rate of a liquid crystal material is controlled based on a product of a liquid crystal amount per drop and the number of drops. As a result, the adjustment takes a lot of time, and furthermore, because the amount per drop is such a minute amount of a few mgs, accurate measurement becomes difficult, even with an electronic force balance. Before feeding the liquid crystal material to a substrate, the liquid crystal material to be dropped from a tank onto the substrate is previously weighed and filled in a microsyringe, and then while the relative position of the substrate and a liquid crystal discharge hole is varied, the liquid crystal filled in the microsyringe is fed onto the substrate surface by dropping only a desired amount of the liquid crystal at the desired position of the substrate.
