Abstract

The invention relates to a transparent substrate for an organic light-emitting device comprising an electrode-bearing carrier, said electrode consisting in a multilayer comprising at least, in order starting from the substrate, a first dielectric layer (D1), a first conduction metal layer (M1), a second dielectric layer (D2), a second conduction metal layer (M2), and a third dielectric layer (D3), the conduction metal layers (M) in the electrode (11) being two in number, and the third dielectric layer (D3) not comprising an indium-oxide-based layer. It is characterised in that the geometric thickness of the second dielectric layer (D2) is at least 65 nm and the geometric thickness of the first conduction metal layer (M1) is at least 8.5 nm.
