An introduction chamber into which a liquid crystal cell into which liquid crystal is injected and a liquid crystal dish containing liquid crystal are provided, and the introduction chamber is provided through the introduction chamber and a gate valve. An injection chamber in which the liquid crystal dish is loaded; a vacuum exhaust system for evacuating the introduction chamber; an inert gas introduction system for introducing an inert gas into the introduction chamber; An approach mechanism for relatively bringing the liquid crystal cell and the liquid crystal dish closer to each other; a separating mechanism for relatively separating the liquid crystal cell and the liquid crystal dish from the injection chamber; Is loaded, and the liquid crystal cell introduced into the introduction chamber is evacuated by evacuation by the evacuation system, and then the liquid crystal injection port of the liquid crystal cell comes into contact with the liquid crystal of the liquid crystal dish by the approach mechanism. So that the inert gas In a liquid crystal injection device that starts injecting liquid crystal into the liquid crystal cell by introducing an inert gas in the introduction system, the liquid crystal injection port of the liquid crystal cell is in contact with the liquid crystal of the liquid crystal dish, and the liquid is injected from the introduction chamber. In order to load the liquid crystal cell and the liquid crystal dish into the injection chamber, a connection comprising a pin and a pin hole for connecting the cassette tray holding the liquid crystal cell and the liquid crystal dish tray on which the liquid crystal dish is mounted to each other. Means is provided, and a sliding means is provided on the mounting surface of the liquid crystal tray tray in the approach mechanism to facilitate movement of the liquid crystal dish tray connected by the connecting means together with the cassette tray moved by the moving means. A liquid crystal injection device characterized by the above-mentioned.
