A method for manufacturing an organic light-emitting device includes forming an anode over a substrate, at least one organic light-emitting layer over the anode, a buffer layer over the organic light emitting layer, and a cathode over the buffer layer. The cathode is formed of first, second and third cathode layers. The first cathode layer is formed of a conductive material. A second cathode layer of electron transport material is formed over the first cathode layer and a third cathode layer of conductive material is formed over the second cathode layer.
