1. A touch control glazing comprising:

  • a first transparent glazing having a first main surface;

    an electrically conductive layer applied on the first main surface of the first transparent glazing;

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

    a light emitting diode arranged on the electrically conductive layer to indicate the touch sensitive area, the light emitting diode having a light emitting surface facing at least partially the touch sensitive area, the light emitting 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 around the touch sensitive area and the light emitting indicator diode being within the touch sensitive area, wherein the light emitting diode is arranged over the dividing line.
