Abstract
A laminated pane, includes an outer pane, an inner pane, and at least two intermediate layers, wherein at least two separate functional elements with electrically controllable optical properties are arranged in a plane between the two intermediate layers, wherein on two opposite sides of each functional element, an inner bus bar is connected in each case to the respective functional element and at least one of the two opposite sides of each functional element is sealed by two PET barrier films, which are partly arranged between an intermediate layer and the functional element, wherein attached on one of the PET barrier films is at least one outer bus bar that is connected via an electrically conducting connection to the inner bus bar of a functional element, in order to electrically control the functional element separately from the other functional element or elements.
