Abstract
The circumferential part of an opening of an ejection part included in a nozzle head is formed in the shape of a convex curved plane. A liquid crystal droplet adhered to the portion with the shape of a convex curved plane of the ejection part smoothly flows down along the outer surface of the ejection part and is adhered to the opening end of the opening. The liquid crystal droplet adhered to the opening end of the opening is absorbed into the liquid crystal droplet to be ejected through the opening and is dispensed downward together with the liquid crystal droplet. This suppresses a large liquid crystal pool being formed on the outer surface of the ejection part. As a result, such problems that liquid crystal to be dispensed is absorbed into a liquid crystal pool while not being dispensed downward and that a large amount of liquid crystal is unnecessarily dispensed from a liquid crystal pool are both be suppressed. In other words, liquid crystal may appropriately be dispensed.
