Abstract
A multiple glazing with variable scattering by liquid crystals can have first and second flat float glass sheets held on the edge of their internal faces by a joint made of a given joint material. In some examples, the glazing also includes first and second electrodes and a layer of liquid crystals with an average thickness E between 5 and 15 μm. The thickness of each of the first and second glass sheets may be less than or equal to 6.5 mm and each of the internal faces coated with the first and second electrodes may have a dioptric defect score, expressed in millidiopters, of less than or equal to 2+2E/3, where the thickness E of the liquid crystals is in μm.
