A glazing unit with electrically controllable optical properties having multiple independent switching regions includes a laminated glass pane with an electrically controllable functional element and a control unit to control the optical properties of the functional element. The functional element has an active layer with electrically controllable optical properties between a first planar electrode and a second planar electrode. The first planar electrode is subdivided by at least one insulation line into at least two separate electrode segments, wherein a voltage is applicable independently between each electrode segment of the first planar electrode and the second planar electrode in order to control the optical properties of the section of the active layer located between them. The control unit is adapted to apply an AC voltage between at least two electrode segments of the first planar electrode and the second planar electrode, wherein the AC voltages are phase-shifted.
