Abstract
The subject of the invention is glazing which incorporates at least one electrically controllable system having variable optical and/or energy properties, especially in the form of a system comprising one or more reversible-insertion materials of the electrochromic-system type, in the form of an optical-valve or viologen-based system or in the form of a liquid-crystal or cholesteric-gel system. This glazing also includes at least one means for adjusting the optical appearance conferred on the said glazing by the said system, these means comprising at least one coating having antireflection properties in the visible.
