An OLED device including a substrate, an anode formed of a conductive material over the substrate, and an emissive layer having an electroluminescent material provided over the anode. The OLED device also includes either an ultrathin cathode over the emissive layer, a thin interlayer over the ultrathin cathode and a reflecting layer over the thin interlayer, or the thin interlayer over the emissive layer and a reflecting layer containing an electron-injecting dopant over the thin interlayer.
