1. A transparent pane, comprising:

  • at least one transparent substrate; and

    at least one electrically conductive coating on at least one surface of the at least one transparent substrate,wherein each at least one electrically conductive coating has at least two functional layers arranged one above the other,wherein each functional layer includesa layer of an optically highly refractive material having a refractive index greater than or equal to 2.1,a smoothing layer containing at least one non-crystalline oxide and being arranged above the layer of an optically highly refractive material,a lower matching layer arranged above the smoothing layer,an electrically conductive layer arranged above the lower matching layer, andan upper matching layer arranged above the electrically conductive layer,wherein at least one of the lower matching layer and the upper matching layer contains a homogeneously distributed getter material in a concentration from 1 wt. % to 10 wt. % selected from the group consisting of niobium, titanium, barium, magnesium, tantalum, zirconium, thorium, palladium, platinum, and alloys thereof, andwherein the electrically conductive layer is in direct contact with the at least one of the lower matching layer or the upper matching layer.
