Abstract
In 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.
