Patent ID: 7161291

Claim:
A display element comprising a first electrode, a luminescent layer, a second electrode, and a transparent substrate, wherein said first electrode comprising a metal layer and a corrosion-resistant charge injection accelerating layer and reflects not more than 70% of light in the visible region incident through the second electrode side; said metal layer comprising a laminate of one or more alloys and one or more metals, said metals being 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, said corrosion-resistant charge injection accelerating layer having been formed by subjecting a surface layer in said metal layer to plasma treatment using an oxygen atom-containing gas and having a lower resistivity than the luminescent layer.
