    • A material for in the fabrication of a luminous display device is described. The material comprises: a glass or vitroceramic substrate, a first layer deposited on one side of said substrate and essentially including at least one transparent conducting oxide (TCO), simple or mixed, doped or not, a second TCO layer of at least one transparent conducting oxide, simple or mixed, doped or not, hereafter called second TCO layer, both TCO layers being such that: the first TCO layer has a roughness of more than 1 nm and the second TCO layer has a roughness less than or equal to 1 nm, transmittance in the visible range of the product having both TCO layers is equal to at least 80%, the work function of the second TCO layer is greater than the work function of the first TCO layer and is greater than 4.6 eV and, preferably, greater than 4.8 eV. The first TCO layer is advantageously an indium oxide layer doped with tin (ITO) and the second TCO layer is a tin oxide layer doped with antimony (ATO). A luminous display devices, in particular to organic light emitting diodes incorporating these materials on their anode side is also described.
