This laminated glass pane comprises at least two superimposed plies (A, B, C) of a transparent substrate, which is mechanically resistant, with the placement of an interlayer (4; 6), which is made of transparent material, between two adjacent plies. The glass pane also comprises, in its thickness or on the surface, at least one thin transparent conductive layer (11) extending over a portion of at least the pane, said layer or said layers (11) being heated for defrosting and/or for defogging by Joule effect, at least one thin layer (11) comprising flux boundary lines formed by engraving for guiding the intensity of current from one strip to the other. The width of these flux boundary lines is selected so that it is small enough to render them invisible to the naked eye in the laminated heated glass pane.
Ce vitrage chauffant feuilleté comprend au moins deux plis superposés (A, B, C) de substrat transparent, mécaniquement résistant, avec interposition entre deux plis voisins d'une couche intercalaire (4 ; 6) en matière plastique transparente. Il comporte en outre, dans son épaisseur ou en surface au moins une couche mince conductrice et transparente (11) qui s'étend sur une partie au moins du vitrage, ladite couche ou lesdites couches (11) étant chauffantes en vue du dégivrage et/ou du désembuage par effet Joule, au moins une couche mince (11) comportant des lignes de séparation de flux formées par gravure pour guider l'intensité de courant d'une bande à l'autre. La largeur desdites lignes de séparation de flux est choisie suffisamment faible pour que celles- ci soient invisibles à l'AEil nu dans le vitrage chauffant feuilleté.
