<p>A switchable film assembly is disclosed. The assembly comprises an active layer, the optical transmission of which changes with an applied voltage, laminated between first and second planar electrode layers. The planar electrode layers comprise a plastics substrate material having an electrically conductive coating disposed on the surface thereof remote from the active layer. At least one region of the plastics substrate material ofthe first planar electrode layer remains uncoated, forming an electrically isolated region, such that that a portion of the active layer remains unswitched when a voltage is applied.</p> |
