Abstract

A transparent layered element includes two transparent external layers having substantially the same refractive index and each having a smooth external main surface, and a central layer intermediate between the external layers, the central layer including at least one transparent layer of refractive index different from that of the external layers or a metal layer. All the contact surfaces between two adjacent layers of the layered element, one of the two layers of which is a metal layer, or that are two transparent layers of different refractive indices, being textured and parallel to one another, the diffuse light reflection of the layered element on the side of at least one of the external layers having at least one maximum in a direction different from the direction of specular reflection. In addition, the surface of the layered element is divided into a plurality of pixels of same size.
