Multiple glazing with variable scattering by liquid crystals and its method of manufacture

A method for producing a multiple glazing unit with variable diffusion by liquid crystals can include applying a pre-seal on an internal face of a first substrate to form a strip delimiting a space. The method can further include depositing a liquid crystal composition containing liquid crystals in a polymer matrix on the delimited space. In some examples, the first substrate is assembled with a second substrate and calendared or pressed. Thereafter, the resulting assembly is irradiated and/or heated to simultaneously cross-link the pre-seal and polymerize the liquid crystal composition.
