An organic electroluminescent device is disclosed which is protected from dark spot formation. The device is comprised of, in sequence, a support, an anode, an organic electroluminescent medium, and a cathode. The cathode is comprised of an electron injecting layer contacting the organic electroluminescent medium containing a plurality of metals at least one of which has a work function of less than that of indium. The cathode is comprised of a layer of fused metal particles containing at least 80 percent of indium and having a mean diameter of less the 1 μm and a coefficient of variation of less than 20 percent. |
