Abstract
A translucent conductive substrate (1) for Organic Light Emitting Device comprising, a transparent support (10), a scattering layer (11) formed over the transparent support (10) and comprising a glass which contains a base material (110) having a first refractive index for at least one wavelength of light to be transmitted and a plurality of scattering materials (111) dispersed in the base material (110) and having a second refractive index different from that of the base material and a transparent electrode (12) formed over the scattering layer (11), said electrode (12) comprising at least one metal conduction layer (122) and at least one coating (120) having properties for improving the light transmission through said electrode, said coating (120) comprises at least one layer for improving light transmission (1201) and is located between the metal conduction layer (122) and the scattering layer (11), on which said electrode (12) is deposited.
