An alternating current thin-film lectroluminescent device includes a plurality of pixel electrodes. An electroluminescent phosphor material is located between a first dielectric layer and a second dielectric layer. A transparent electrode layer, wherein at least a portion 10 of the electroluminescent phosphor material and the first and second dielectric layers are located between the pixel electrodes and the transparent electrode layer. The first dielectric layer is closer to the transparent electrode layer than the second dielectric layer. A non-uniform substantially non-conductive light absorbing material is located between the transparent electrode layer and the first dielectric layer.
