Abstract
An organic light emitting device structure includes a substrate, a first electrically conductive layer formed over the substrate wherein the first electrically conductive layer has a positive polarity, and a transparent organic light emitting device formed over the first electrically conductive layer. The structure also includes a transparent electrically conductive metal layer formed over the transparent organic light emitting device wherein the metal has a work function less than 4 eV, and a second electrically conductive layer formed over the transparent electrically conductive metal layer, wherein the second electrically conductive layer has a negative polarity, and wherein the second electrically conductive layer comprises a material selected from the group consisting of a transparent electrically conductive oxide and a transparent electrically conductive polymer.
