Zusammenfassung:The present invention relates to a thin-film electroluminescent device providing improved optical properties. An alternating current thin-film electroluminescent 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 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. The phosphor material is patterned.
