Abstract

La présente invention a trait à une structure multi-couches diffusante plane (20) comportant : un premier élément substrat (23) d'indice de réfraction ni dans le visible, choisi parmi un verre, un plastique, un oxyde de titane; un deuxième élément (21) qui est diffusant et sur une première face principale du premier élément; une couche bas indice (22), disposée entre le premier élément et le deuxième élément et au moins en contact optique avec les premier et deuxième éléments, l'élément bas indice étant sensiblement transparent, d'épaisseur supérieure ou égale à 100 nm, et d'indice de réfraction n2 dans le visible, la différence nl-n2 étant supérieure ou égale à 0,1. Le deuxième élément est une couche soit continue ayant une épaisseur variable soit discontinue. L'invention porte aussi sur son procédé de fabrication et ses applications.
