Zusammenfassung:PURPOSE:To provide a liquid crystal injection device which suppresses the useless consumption of liquid crystals and supplies the liquid crystals into liquid crystal cells without staining the parts near the injection ports in the liquid crystal cells and without the infiltration of foreign matter, etc. CONSTITUTION:This liquid crystal injection device has liquid crystal supply means 2 in the positions corresponding to the injection ports 6 of the liquid crystal cells 1 and has connecting fittings 3 which move vertically in three steps in order to fix these liquid crystal supply means 2 and to supply, defoam and inject the liquid crystals. Then, the local contact of only the injection ports with the liquid crystals 4' is resulted without immersing the entire part on the injection port side in the liquid crystal cells 1 into the liquid crystals 4 and since the liquid crystals are directly injected into the liquid crystal cells without intervening a medium during this time, the liquid crystals are efficiently injected into the liquid crystal cells without staining the parts near the injection ports and without the infiltration of the foreign matter.
