Abstract
An antireflective switchable laminated glass construction having a switchable functional film formed of a switchable material layer, a first polymer substrate with a first transparent conductive coating, and a second polymer substrate with a second transparent conductive coating. The switchable functional film is sandwiched between first adhesive polymer interlayer and glass substrate and second adhesive polymer interlayer and glass substrate. The switchable laminated glass construction in an ON (transparent) state has a total light transmittance higher than 50% and a reflectance equal to or less than 13%, as measured from at least one side of the switchable laminated glass construction.
