1. A privacy glazing structure comprising:
a first pane of transparent material having an inner face, an outer face, and a peripheral edge;
a second pane of transparent material having an inner face, an outer face, and a peripheral edge;
a first electrode layer on the inner face of the first pane of transparent material;
a second electrode layer on the inner face of the second pane of transparent material;
an electrically controllable optically active material positioned between the first electrode layer on the inner face of the first pane of transparent material and the second electrode layer on the inner face of the second pane of transparent material;
wherein the first pane of transparent material is generally parallel to the second pane of transparent material to form a cavity therebetween containing the electrically controllable optically active material, and
the first pane of transparent material defines a notch providing access to two electrical contact portions carried by the inner face of the second pane of transparent material, a first of the two electrical contact portions being electrically connected to the first electrode layer and a second of the two electrical contact portions being electrically connected to the second electrode layer.
