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.
