Abstract

A white-light-emitting tandem OLED device having spaced anode and cathode including: first and second light-emitting units disposed between the anode and cathode; an intermediate connector including an n-type layer and a p-type layer disposed between the first and second light-emitting units; and a fluoranthene-containing electron-transporting layer adjacent to the n-type layer of the intermediate connector and including at least 25% of a 7,10-diaryl-substituted fluoranthene compound having no aromatic rings annulated to the fluoranthene nucleus.
