Patent ID: 8786176

Claim:
A substrate for an organic light-emitting device, comprising a transparent substrate having an optical index n 0 , bearing, on a first main face, a first transparent or semi-transparent coating of an electrode and which comprises: an anti-reflection sublayer having a first optical thickness and having an optical index n 1 such that the ratio of n 1 to n 0 is greater than or equal to 6/5; a first metallic layer having a second thickness, positioned on the anti-reflection sublayer; an overlayer for adapting a work function of the first transparent or semi-transparent coating of the electrode and comprising a metal oxide selected from the group consisting of a mixed indium tin oxide, a mixed indium zinc oxide, a mixed oxide of zinc and tin, and a mixture thereof, having a third thickness, positioned on the first metallic layer, wherein the overlayer is the last layer of the electrode so as to be provided between an OLED system of the organic light-emitting device and the substrate; a first separating layer, having a fourth optical thickness, positioned on the first metallic layer and beneath the overlayer; a second metallic layer, having an intrinsic electrical conductivity property, and having a fifth thickness, said second layer being positioned between the first separating layer and the overlayer; wherein the first optical thickness is between 20 nm and 120 nm, the fourth optical thickness is between 75 nm and 200 nm, and the sum of the second and fifth thicknesses of the first and second metallic layers is less than or equal to 40 nm; and wherein the electrode has a sheet resistance less than or equal to 6Ω/□.
