1. A multilayer electronic device, comprising:

  • an organic polymer layer; and

    an electrode positioned against the polymer layer, the electrode being constituted by a transparent stack of thin layers comprising an alternation of n thin metallic layers and of (n+1) antireflection coatings, with n≧

    1, where each thin metallic layer is placed between two antireflection coatings,wherein the electrode comprises;

    a first barrier stack, which is a barrier to moisture and to gases, in the end antireflection coating which is placed under the n thin metallic layers in the direction of deposition of the constituent stack of the electrode, the first barrier stack comprising at least four layers having alternately lower and higher densities,and/ora second barrier stack, which is a barrier to moisture and to gases, in the end antireflection coating which is placed on top of the n thin metallic layers in the direction of deposition of the constituent stack of the electrode, the second barrier stack comprising at least three layers having alternately lower and higher densities.
