The invention concerns a laminated glass pane (1) with at least a rigid pane and a flat electrically controlled functional element (2) as well as at least a thin electrically conductive coat (5), wherein, in accordance with the invention, the coat (5) also constitutes a flat electrode of the functional element, the coat being capable of being heated by being powered with an electric voltage, independently of the power supply of the functional element (2). Thus, unwanted variations of the optical properties of the functional elements are reduced when such a laminated glass pane is used at highly fluctuating temperatures, in particular at low temperatures.
