A privacy glazing structure may include an electrically controllable optically active material, such as a liquid crystal material, sandwiched between a flexible substrate and a rigid substrate. The flexible substrate and the rigid substrate may each have a conductive layer deposited on the surface facing the optically active material. The flexible substrate may be bonded about its perimeter to the rigid substrate and may be sufficiently flexible to conform to non-planarity of the rigid substrate. As a result, the flexible substrate may adopt the surface contour of the rigid substrate to maintain a uniform thickness of optically active material between the flexible substrate and the rigid substrate.
