Abstract
The invention relates to a diffuserintended to be facing a light sourcecomprising a transmission layerand a diffusion layerintended to diffuse a light transmitted by the light source, the diffuser being characterised in that the diffusion layer comprises a plurality of metal structures, called metal nanostructures, having dimensions less than a wavelength of the light transmitted, said metal nanostructures having varied sizes and being distributed within the diffusion layer such that adjacent metal nanostructures have between them, varied distances and preferably less than the wavelength of the light transmitted. The invention also relates to a method for manufacturing such a diffuser, and a display system comprising such a diffuser.
