International ClassesB32B 031/20B32B 031/28 Foreign Application Priority Data1989-01-26 DEAbstractIn a process to manufacture a liquid crystal cell, one of the two plates is provided with an adhesive edge strip. A quantity of liquid crystal which is required to form the liquid crystal layer is applied to one of the two plates and the two plates are brought together and positioned in the vacuum and bonded tightly together by the adhesive curing.By the fact that the plates with the correct quantity of liquid crystal on one of the plates are joined together in the vacuum, it is no longer necessary to evacuate the inner space between the plates in a time-comsuming process and apply liquid crystal through a small filling hole in another time-consuming process.Field of SearchOptically transparent glass sandwich making (e.g., window or filter)With air evacuation between laminae Direct application of vacuum or fluid pressure during bonding Of laminae having opposed facing areas out of contact Evacuated or fluid pressure chamber Nonuniform heating Applying pressure before electrical, magnetic, or radiant energy With application of adhesive With application of adhesive To polymerize or cure material in work | |
