    Abstract: A cathode structure for use in an OLED device having one or more OLED layers includes a thin light-transmissive layer having a top surface and a bottom surface and including silver (Ag) wherein the Ag acts as a conductor for the cathode structure, and a light-transmissive electron-injecting layer disposed in contact with the bottom surface of the thin light-transmissive layer and with an underlying OLED layer. The structure also includes an oxide layer disposed over the thin light-transmissive layer, and a separation layer disposed between the top surface of the thin light-transmissive layer and the oxide layer.
