ABSTRACT:
A method is disclosed for the manufacture of cells having a hollow space adapted to lodge a liquid crystal, such cells being used, for example, in various display devices. The essence of the method is to induce in the supporting members forming the walls of the cell an elastic deformation and to maintain the confronting cell surfaces pressed together with the interposition of appropriate spreaders. Such elastic deformation is originated by imparting an appropriate curvature to at least one of the supporting members prior to uniting them and welding them together. Critical values for the radius of curvature are given, as well as for the spreader interspaces.
