A display device including a top support plate having a first refractive index. A diffusion layer on a first surface of the top support plate includes a plurality of features. Each feature of the plurality of features has a second refractive index greater than the first refractive index. A transparent conductive polymer layer is applied over the diffusion layer. The transparent conductive polymer layer has a third refractive index equal to the first refractive index, and provides a common electrode.
