Abstract
One end of a vacuum evacuation passage is connected to a suction port of a cell and one end of a liquid crystal supply passage is connected to an introduction port of the cell. In that state, an internal space of the cell is evacuated through the vacuum evacuation passage and the suction port. Thereafter, a pressurized liquid crystal is supplied to the internal space of the cell through the liquid crystal supply passage and the introduction port while evacuating the internal space of the cell. After the completion of a liquid crystal filling operation to the internal space of the cell, the supply of the pressurized liquid crystal is stopped and the level of the negative pressure in the vacuum evacuation passage is gradually eased to the level of the atmospheric pressure.
