    摘要: The invention relates the field of light boxes, and more specifically to a diffusing layer intended to be deposited on a substrate for making a light source homogeneous. The diffusing layer according to the invention consists of agglomerated semitransparent mineral particles in a mineral binder and is characterized by the particles having a mean diameter of between 0.3 and 2 microns, the binder being in a proportion of between 10 and 40% by volume, the particles forming aggregates whose size is between 0.5 and 20 microns, preferably less than 5 microns, and the layer having a contrast attenuation of greater than 40%. The invention also relates to uses for the production of flat lamps.
