Abstract: A device includes a first electrode, an organic layer disposed over the first electrode and a second electrode disposed over the organic layer. The second electrode includes a first conductive layer, a first separation layer disposed over the first conductive layer, and a second conductive layer disposed over the first separation layer, wherein the first separation layer is not a continuous layer and the first and second conductive layers are bridged where the first separation layer is not continuous. The first separation layer has an extinction coefficient that is at least 10% different from the extinction coefficient of the first conductive layer at wavelength 500 nm, or an index of refraction that is at least 10% different from the index of refraction of the first conductive layer at wavelength 500 nm.
