Abstract

PURPOSE:To provide a liquid crystal discharging device which discharges a predetermined amount of liquid crystal by means of rotation of a shaft and applies it to the inner surface of a panel substrate, as do liquid crystal dropping devices used in a liquid crystal injection process involved in the assembling process of e.g. a liquid crystal display panel. CONSTITUTION:While a shaft 4 is being stopped, liquid crystal is not dropped from an end of a nozzle 3. When the shaft 4 is rotated via a rotary mechanism, the liquid crystal 7 present in the clearance between the shaft 4 and the inner surface of a sleeve 5 is pushed down toward the end of the nozzle 3 due to a spiral groove and can be dropped. The amount of dropping of the liquid crystal 7 can freely be varied by varying the number of revolutions of the shaft 4, or the form or angle of the groove 101.
