摘要 |
An organic electroluminescent device (100) is disclosed which is protected from dark spot formation. The device (100) is comprised of, in sequence, a support (102), an anode (104), an organic electroluminescent medium (106), and a cathode (118). The cathode (118) is comprised of an electron injecting layer (120) contacting the organic electroluminescent medium (106) containing a plurality of metals at least one of which has a work function of less than that of indium. The cathode (118) is comprised of a layer of fused metal particles containing at least 80 percent indium and having a mean diameter of less than 1 mu m and a coefficient of variation of less than 20 percent. <IMAGE> |
