Abstract: According to one embodiment, the liquid crystal material processing device includes a syringe containing contents composed of a liquid crystal material and the like, having a distal end portion constituting a first discharge pipe, an agitation mechanism agitating the contents of the syringe, a vacuum chamber having a second discharge pipe penetrating the bottom to connect to the first discharge pipe of the syringe. The agitation mechanism agitates the liquid crystal material and the pure water in the syringe, and purifies the liquid crystal material by causing water-soluble impurities to transfer to the pure water. The agitation mechanism agitates the liquid crystal material remaining in the syringe after the water layer has been discharged. The evacuation mechanism evacuates the vacuum chamber and causes the liquid crystal material to be degassed while the remaining liquid crystal material is agitated.
