Abstract

PURPOSE:To perform a hardening process for a sealant under reduced pressure by discharging quickly generated gas to the outside of a cell. CONSTITUTION:A liquid crystal cell 14, a flexible partition wall film 18, and an upper mold 19 are disposed on a lower mold 16, and either of a lower space 24 and an upper space 25 is made reduceable in pressure. A valve 21 is closed and a valve 20 is opened to evacuate the inside of the space 24 by an evacuation pump 17 to maintain said space under -0.2-1kg/cm<2> reduced pressure. The gas such as oxygen, moisture or the like stuck on the electrode surface of the liquid crystal cell is thus discharged. The cell is then heated to 100-200 deg.C or is irradiated with UV light to harden the sealant. If gas is generated from the sealant in this stage, the gas is also discharged to the outside of the cell without sticking on the electrode surface. The valve 20 is closed and the valve 21 are opened upon hardening of the seal to introduce dry air, gaseous N2 or the like, then the pressure reduction in the lower space 24 is released to restore atm. pressure.
