Abstract

PURPOSE:To inject from the upper direction and to improve productivity drastically greatly, by impregnating liquid crystals into an impregnating body and injecting them to a cell. CONSTITUTION:A liquid crystal injecting device consists of a liquid crystal replenishing vessel 11, an introducing tube 12, an introducing pipe and an impregnating body 17. In order to inject a liquid crystal into a cell 14, the cell and the liquid crystal injecting device are set in a vacuum vessel the impregnating body 17 of the liquid crystal injecting device is bronght into contact with an opening part 16 of the cell 14. Then, when air is introduced into the vacuum vessel, a liquid crystal 15 impregnated in the inpregnating body 17 by air pressure flows is the cell 14 from the opening part 16. After impregnating sufficiently the impregnating body 17 with the liquid crystal 15 before injecting, if, by lowering the liquid crystal replenishing vessel 11 from the introducing pipe 18 to the lower part, liquid crystal supply to the impregnating body 17 is interrupted and only a liquid crystal of a necessary injection amount is impregnated previously in the impregnating body 17, an amount of consumption of the liquid crystal 15 is reduced.
