Zusammenfassung:	The present invention relates to a liquid material ejecting unit, a liquid material ejecting device, and a liquid material ejecting method thereof. The liquid material ejecting unit ejects a liquid material such as liquid crystals onto a substrate. The liquid material ejecting device applies the same. According to an embodiment of the present invention, the liquid material ejecting unit includes: a syringe which has an internal spaced filled with the liquid material and a nozzle connector connected to the internal space; a nozzle which is connected to the nozzle connector to discharge the liquid material; a compressor which is made of an elastic material and is arranged to face the nozzle connector; a compression actuator which is arranged on the inner space of the syringe and is coupled to an end of the compressor to compress the compressor to the floor surface of the syringe; and a control unit which controls the compression actuator to space the compressor and the nozzle connector apart or make the adjacent surfaces of the compressor and the nozzle connector come in contact with each other to discharge the liquid material through the nozzle. 본 발명은 액상물 토출 유닛 및 액상물 토출 장치 및 액상물 토출 방법으로서, 액정 등과 같은 액상물을 기판에 토출하는 액상물 토출 유닛 및 이러한 액상물 토출 유닛이 적용한 액상물 토출 장치 및 액상물 토출 방법에 관한 것이다. 본 발명의 실시 형태인 액상물 토출 유닛은, 액상물이 채워지는 내부 공간을 가지며, 상기 내부 공간에 연결된 노즐 연결구가 형성된 실린지; 상기 노즐 연결구와 연결되어 액상물을 토출하는 노즐; 탄성체 재질을 가지며, 상기 노즐 연결구에 대향하여 위치하는 압축기; 상기 실린지의 내부 공간에 마련되며, 상기 압축기를 끝단에 결합하여 상기 압축기를 실린지의 바닥면에 압축시키는 압축 구동기; 상기 압축기와 상기 노즐 연결구가 이격되도록 하거나, 또는 상기 압축기와 노즐 연결구의 주변면이 밀착되도록 하여 상기 노즐을 통하여 액상물이 토출되도록 상기 압축 구동기를 제어하는 제어부;를 포함한다.
