Zusammenfassung:	The present invention relates to an apparatus of dispensing materials and a method of operating the same. The apparatus of dispensing materials comprises: a housing which includes an inner space having a passage through which materials move and at least one dispenser which is installed at the lower portion of the housing and has a nozzle to discharge materials; a shutter which is placed in the inner space of the housing to open/shut the passage; and a gas supplier which is connected to one side of the housing to supply gas into the inner space of the housing and thus control the dispensed amount of materials. The method of operating the apparatus comprises the steps of: injecting materials into the inner space communicated to the nozzle; injecting gas into the inner space to seal the same with an opening/closing member; dispensing materials; and stopping the injection of gas to unseal the inner space with the opening/closing member. The present invention enables easy division of liquid crystal into uniform size so that the liquid crystal can be applied uniformly across the whole region of a substrate. 본 발명은 기판 상에 원료를 토출하는 원료 토출 장치 및 이를 이용한 원료 토출 방법에 관한 것으로서, 원료가 이동하는 경로를 형성하는 내부공간을 구비하는 하우징 및 하우징의 하부에 장착되어 원료를 토출하는 노즐을 구비하는 적어도 하나 이상의 디스펜서와, 내부공간 내에 적어도 일부가 배치되어 경로를 개폐하는 차단기 및 차단기가 배치되는 하우징의 일측에 연결되어 내부공간 측으로 가스를 공급하여 원료의 토출량을 제어하는 가스 공급기를 포함하여, 노즐과 연통된 내부공간으로 원료를 주입하는 단계와, 내부공간으로 가스를 취입하여 개폐부재로 내부 공간을 폐쇄하는 단계, 원료를 토출하는 단계 및 가스의 취입을 중단하여 개폐부재로 내부 공간을 개방하는 단계를 포함함으로써, 액정을 균일한 크기로 용이하게 분할할 수 있어, 기판의 전 영역에 걸쳐 액정을 균일하게 도포시킬 수 있다.
