Abstract
A support for an organic light-emitting diode device successively includes a transparent substrate, made of mineral glass, provided with first and second opposite main faces, the substrate being coated on its second face with a diffusing layer which includes a vitreous mineral binder and diffusing elements dispersed in the binder, the vitreous binder includes between 40% and 60% by weight of bismuth oxide Bi2O3 inclusive of these values, or even between 45% and 58% by weight of bismuth oxide Bi2O3 inclusive of these values, and the proportion of the vitreous binder is at least 20% of the total weight of the diffusing layer.
