1. A lighting laminated glazing comprising:

  • a first transparent glazing;

    a second glazing;

    an intermediate layer made of thermoplastic material, laminating the second glazing to the first transparent glazing;

    an electrically conductive layer disposed between the first transparent glazing and the second glazing, preferably transparent;

    a capacitive touch sensitive device comprising a capacitive touch sensitive structure formed in said electrically conductive layer, the capacitive touch sensitive structure comprising a ground electrode and a touch electrode having a touch sensitive area wherein the touch electrode is surrounded by the ground electrode, the touch electrode and the ground electrode being electrically insulated from one another by a dividing line;

    a light emitting indicator diode, arranged on the electrically conductive layer to indicate the touch sensitive area, the light emitting indicator diode having a light emitting surface facing at least partially the touch sensitive area, the light emitting indicator diode having a first terminal being a first electrode zone electrically connected to the ground electrode and a second terminal being a second electrode zone electrically connected to the touch sensitive area and said first electrode zone disposed within the touch sensitive area and the light emitting indicator diode being within the touch sensitive area;

    a lighting device controlled by the capacitive touch sensitive device, the lighting device comprising a lighting element distinct from the light emitting indicator diode, the lighting element being disposed between the first transparent glazing and the second glazing.
