The present invention relates to an article comprising at least one glass-ceramic substrate, in particular a plate, intended, for example, to cover or receive at least one heating element, said substrate exhibiting, in at least one zone, a surface roughness such that the characteristic dimensions of the patterns forming said roughness are between 2 and 100 &#x3bc;m. The present invention also relates to an advantageous process for producing said substrate.

Glass-ceramic article and manufacturing process

A transparent diffusive OLED substrate includes (a) a transparent flat substrate made of mineral glass having a refractive index of between 1.45 and 1.65, (b) a rough low index layer including mineral particles, the mineral particles being attached to one side of the substrate by means of a sol-gel mineral binder, the mineral particles near, at or protruding from the mineral binder's surface creating a surface roughness characterized by an arithmetical mean deviation Ra comprised between 0.15 and 3 &#x3bc;m, the mineral particles and mineral binder both having a refractive index of between 1.45 and 1.65; (c) a high index layer made of an enamel having a refractive index comprised between 1.8 and 2.1 covering the rough low index layer.
