Abstract:
A light extraction substrate includes a glass substrate having a first surface and a second surface. A first light extraction region can be defined on and/or adjacent the first surface. The first light extraction region includes nanoparticles. A second light extraction region can be defined on at least a part of the second surface. The second light extraction region has a surface roughness of at least 10 nm.
