Abstract
A method of manufacturing an electro-optical cell in which at least one insulating lamina of adhesive material bonded to at least one spacer element and having an opening defining the limits of the cell is introduced between two cell walls, and the walls are then heated and compressed to soften the adhesive material and seal the cell. The cell may have a spacer element in the form of a lamina of plastics material or may have a number of metallic spacer elements which provide electrical connections to conductive elements carried on a wall of the cell.
