<p>A glazing having electrically controllable optical transmission properties having, in at least one electrically controllable state, a light transmission TL greater than or equal to 60%, the glazing comprising: - two sheets having a glass function (2A, 2B); and - between the two sheets having a glass function, an active system (4) having electrically controllable optical transmission properties, in which the glazing further comprises a transparent and reflective stack of thin layers (6) comprising: - a functional metal layer; and - a coating made from a dielectric material with a high optical index and a sufficient optical thickness for the glazing to have three reflection peaks at three visible wavelengths.</p> |
