Abstract
A multiple glazing with variable scattering by liquid crystals includes first and second flat float glass sheets sealed on the edge of their internal faces by a sealing joint, in particular made of a given sealing material, in particular essentially organic, first and second electrodes, and a layer of liquid crystals with an average thickness E between 15 and 60 μm inclusive of these values and incorporating spacers. The thickness A of each of the first and second glass sheets is less than or equal to 5.5 mm, and each of the internal faces coated with the first and second electrodes has a dioptric defect score, expressed in millidioptres, of less than 12E/15 where the thickness E of the liquid crystals is in μm.
