Abstract
The subject of the invention is a glazing panel comprising a transparent substrate (1), especially one made of glass, provided with at least one functional, conductive and/or low-emissivity, transparent thin film (3). In order to improve the optical and especially the calorimetric appearance of the glazing panel, at least one intermediate film (2) is placed between the substrate (1) and the functional film (3), this at least one intermediate film having a refractive index gradient decreasing through its thickness. The invention also relates to the device intended for manufacturing this type of glazing panel.
