摘要： The transparent conductive layer-built-up material based on the present invention, since it is of the construction that, in a transparent conductive layer-built-up material comprising a base having thereon at least a transparent conductive layer comprised principally of an oxidized product, the transparent conductive layer has on the obverse side thereof a metal or a surface layer containing a metal oxide whose oxidation rate is lower than the intrinsic oxidation rate of the transparent conductive layer, exhibits a high adhesive strength when made adhere to, e.g., the luminescent light-emitting layer of a luminescent display unit and adequately satisfactory sheet resistance and light-transmissivity values, thus showing very excellent characteristics as of a transparent conductive layer-built-up material. Accordingly, if the transparent conductive layer-built-up material based on this invention is used as the transparent conductive layer-built-up material for, e.g., an electroluminescent display unit, the displayed pattern is excellent in the luminance as well as in the contrast, and thus a clear image can be obtained.
