PURPOSE:To inject simultaneously to a pair of empty cells without dropping of an liquid crystal by injecting the liquid through a liquid crystal impregnating body to a pair of liquid crystal cells coupled back to back. CONSTITUTION:A liquid crystal injecting device set in the upper direction consists of a liquid crystal replenishing vessel 11, a liquid crystal introducing pipe 18 in the liquid crystal replenishing vessel 11 and a liquid crystal impregnating body 17 equipped to the liquid crystal introducing pipe 18. When a liquid crystal is injected into a cell, the whole of a divice is set in a vacuum vessel. After impregnating sufficiently the liquid crystal impregnating body 17 with a liquid crystal, if supply of a liquid crystal to the impregnating body 17 is interrupted by lowering the liquid crystal impregnating vessel 11 in the under direction from the liquid crystal introducing part 18, thus only a liquid crystal of a necessary unjection amount is impregnated previously in the impregnating body 17, an amount of consumption of the liquid crystal is reduced. When air is introduced into the vacuum vessel, the liquid crystal flows in the cell with air pressure. |
