ABSTRACT:
A liquid crystal cell consisting of two planar supports and a spacer interposed between them only on the margin, said supports being fixed at intervals of a limit by the spacer to form an aperture, has at least one opening through which the liquid crystal material is poured into said aperture. The openings are sealed with use of cyanoacrylates or polybutadiene type resins so that the liquid crystal cell can be prevented from lowering of the characteristics caused by incorporating of impurities into the liquid crystal layer.
