Aglazing, comprising:
- a) at least one active layer;
- b) at least one reflecting coating on said active layer;
- c) two electrically conductive layers;
- d) two transparent substrates, at least one of which is rigid;
- and
- e) a gas layer;
- wherein the active layer comprises at least one optically variable layer which is an electrically controllable system, which system is a variable light diffusion system, comprising a composite polymer film having embedded therein droplets of liquid crystals, wherein the ordinary index of said liquid crystals, no, is equal to the index of said polymer, np;
- and
- wherein the variable light diffusion system is placed between the two electrically conductive layers, and said gas layer is placed between the two transparent substrates.
