A laminate for a light emitting device, includes a glass substrate, a random network of reliefs formed on the glass substrate, and a flattening layer formed on the network, wherein the network of reliefs are formed from a glass frit. The laminate for a light emitting device further includes a network inducing the scattering of light for efficiently extracting outward a loss of light at an interface between a glass substrate and an internal light extraction layer. The laminate is suitable for the industrial field of optical devices, such as organic light emitting diodes (OLEDs), backlights, lighting, and the like.
