A liquid crystal injecting device has a jig which seals an opening used as a liquid crystal inlet of the cell and another opening used as an air outlet of the cell separately. When obtaining a liquid crystal element by injecting liquid crystal into the cell, the liquid crystal is applied to the inlet before the injection, and after an internal pressure of the cell is reduced by releasing air from the jig, the liquid crystal is injected to the cell by being supplied to the inlet through a liquid crystal supplying tube. During the injection, a temperature of the cell is set to a temperature at which the liquid crystal takes a nematic, cholesteric, or isotropic phase, while air is kept being released. When the injection ends, the liquid crystal is further applied to the inlet and outlet, while being reinjected into the cell through all the openings at room temperature or above under atmospheric pressure or above, after which the cell is cooled.
