Abstract
A laminated heated glazing including at least two superposed transparent and mechanically strong substrate panes with interposition of an interlayer made of a transparent plastic between two adjacent panes. The glazing further includes, in its thickness or on the surface, at least one thin transparent conductive film that extends over at least part of the glazing, the film or films being heated for deicing and/or demisting by Joule effect, at least one film having flow separation lines formed by etching to guide current from one band to the other. The width of the flow separation lines is small enough for them to be invisible to the naked eye in the laminated heated glazing.
