A luminous automotive-vehicle glazing unit includes a first glazing pane, made of organic or mineral glass, of refractive index n1 of at least 1.4 with first and second main faces; a light source coupled to the first glazing pane; and a light-extracting system including a scattering layer of width of at least 1 cm including scattering dielectric particles bound by a transparent matrix of refractive index n2. The scattering particles are mainly microparticles that are spaced apart from one another and that include a shell made of a transparent dielectric material and making contact with the transparent matrix, the shell surrounding a core of refractive index n3 of at most 1.15 and of largest dimension called D3 in a range extending from 5 μm to 200 μm, the microparticles having a largest dimension D′ smaller than 2D3.
