Abstract

A transparent pane comprising a transparent substrate and an electrically conductive coating on a surface of the transparent substrate is disclosed. The electrically conductive coating comprises four functional layers arranged one atop another. Each functional layer comprises a layer of optically highly refractive material with a refractive index >1.3, a first matching layer above the layer of optically highly refractive material, an electrically conductive layer above the first matching layer, and a second matching layer above the electrically conductive layer. The layer thickness of each conductive layer can be 5 nm to 25 nm and the total layer thickness of all electrically conductive layers can be 20 nm to 100 nm.
