Abstract
A layered element includes two transparent outer layers having approximately the same refractive index and each having a smooth outer main surface, the layered element including a screen zone with properties of diffuse reflection and specular transmission comprising a textured middle layer interposed between the outer layers, a peripheral zone with properties of specular reflection and specular transmission, and a transition zone with properties of diffuse reflection and specular transmission between the screen zone and the peripheral zone, which includes a textured middle layer interposed between the outer layers. The diffuse light reflection at any point of the transition zone is less than or equal to the diffuse light reflection at any point of the screen zone and the variation of the diffuse light reflection in the transition zone from the screen zone to the peripheral zone, in any direction joining the screen zone to the peripheral zone, is decreasing.
