Abstract
The invention concerns glass panels comprising thin layers in particular for providing them with solar protective or low-emissive properties, and also comprising other thin layers for correcting rainbow effects induced by the former. The invention is characterized in that said glass panels comprise a glass substrate coated with an aluminum oxynitride layer, deposited by gas phase pyrolysis, and whereof the characteristics of thickness and refractive index are selected so as to attenuate colors reflected by the layer providing the glass panel with low-emissive and/or solar protective properties, layer which is deposited on the aluminum oxynitride layer.
