1. A process for producing a display element comprising the steps of:

  • forming a metal layer on a substrate;

    forming an alloy layer on the metal layer to form a laminate comprising at least the metal layer and the alloy layer, wherein said alloy layer comprises an alloy selected from the group consisting of Cr—

    Mn—

    Si, Cr—

    Mn—

    C—

    Si, Cr—

    Ni—

    C;

    performing patterning on the top of the laminate;

    subjecting the surface of the alloy layer of the laminate to plasma treatment using an oxygen atom-containing gas to convert the surface of the alloy layer to a corrosion-resistant charge injection accelerating layer to form a first electrode comprising the metal layer and the corrosion-resistant charge injection accelerating layer, wherein said alloy layer comprising Cr-base alloy or Ni—

    Cr-base alloy, and said metal layer comprising metals selected from the group consisting of chromium (Cr), nickel (Ni), tungsten (W), manganese (Mn), indium (In), tin (Sn), zinc (Zn), molybdenum (Mo), vanadium (V), titanium (Ti), tantalum (Ta), niobium (Nb) and a mixture thereof;

    forming a luminescent layer on the corrosion-resistant charge injection accelerating layer;

    wherein, the first electrode is an anode, and the second electrode is a cathode.
