摘要：
The invention relates to a substrate (1) carrying a composite electrode (2) on a main face (11), said composite electrode comprising an electroconductive network (21) consisting of strands of an electroconductive material based on metal and/or metallic oxide, and having a light transmission of at least 60 % at 550 nm, the space between the strands of the network being filled by a so-called insulating filling material. The composite electrode also comprises an electroconductive coating (22) covering the electroconductive network and electrically connected to the strands, said coating having a thickness higher than or equal to 40 nm, and a resistivity pi lower than 105 Ohm. cm and higher than the resistivity of the network. The coating forms a smoothed outer surface of an electrode. The composite electrode also comprises a square resistance lower than or equal to 10 Ohm/square. The invention also relates to the production of the composite electrode and to an organic electroluminescent device (100) comprising said electrode.
