To provide a novel method for injecting to a display cell which swivels a cell member in a longitudinal direction in bringing the injection port of the cell member into contact with a liquid material and a injecting device therefor.

The cell member 1 having a sealing chamber 3 and the injection port 30 is used. The cell member 1 is so arranged that the injection port 30 of the cell member 1 and the liquid material L are held without contact. The pressure in the reduced pressure chamber 63 is reduced via the injection port 30 in this state. Next, the cell member 1 is swiveled along the longitudinal direction together with a pressure reduction chamber 6 to bringing the injection port 30 and the liquid material L into contact. Next, the pressure in the reduced pressure chamber 63 is increased to inject the liquid material L into the sealing chamber 3. A cell member fixing means 65 has a function to fix the cell member 1 to the reduced pressure chamber 63. A swiveling driving means 64 has the function to swivel the pressure reduction chamber 6 in the longitudinal direction together with the cell member 1.
