Abstract:
1. An active matrix electroluminescence display device, comprising: a plurality of transistors formed on a substrate having an emissive area and a non-emissive area defined thereon; an insulating layer formed on the substrate and the transistors; a metallic protective layer formed on the insulating layer entirely over one or more transistors of the non-emissive area and not over switching transistors of the emissive area that control emission of light from pixels of the display device; a first electrode formed on the insulating layer of the emissive area; an electroluminous layer formed on the first electrode; and a second electrode formed on the electroluminous layer, wherein the metallic protective layer is electrically coupled to a circuit to reduce capacitance between the metallic protective layer and the one or more transistors covered by the metallic protective layer.
