HOLLOW-SPACE CELL AND METHOD FOR ITS MANUFACTURE ABSTRACT OF THE DISCLOSURE .- 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 planar supporting members which make up the cell walls internal stresses to maintain the confronting cell surfaces pressed together with the interposition of appropriate spreaders. Such internal stresses are originated by imparting an appropriate curvature to 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 . -
