Device for displaying a real image on a glazing unit of a passenger compartment or a facade, said glazing unit comprising on its face exposed to said source a coating that prevents reflection of incident monochromatic laser radiation emitted by a source scanning a portion of said glazing unit, said stack consisting of a stack of two layers, namely, starting from the glazing function substrate, a first layer made of a material based on zinc oxide, tin oxide, silicon nitride, a zinc tin oxide or a zirconium silicon oxide; and a second layer made of a material based on a silicon oxide, in which the respective geometric thicknesses Ep1 and Ep2 of said layers are substantially equal to: for the first layer: Ep1=26+0.07(&thetas;)−0.007(&thetas;)2   (1) for the second layer: Ep2=83−0.1(&thetas;)+0.01(&thetas;)2   (2), in which &thetas; is the mean angle of orientation of the incident monochromatic laser radiation to the normal to said glazing unit, in the scanned portion of the glazing unit. |
