Abstract (en)
[origin: WO0016361A1] A top emitting organic light emitting device (10) includes a substrate (300), a cathode conductor layer (400) having a low work function refractory metal layer (450), an organic light emitting material layer (200), and an anode layer (100). The low work function refractory metal layer (450) preferably is selected from a nitride, boride, or carbide of Ti, Zr, Hf, Nb, W, Mo, Cr, Ta, and V.
