Abstract
An active matrix electroluminescence device and a method for fabricating the same for enhancing electrical characteristics of a wire are disclosed. The method includes forming a wire on a non-emissive area of a substrate, and forming transistors on an emissive area of the substrate, forming an insulating layer on the substrate, the wire, and the transistors, and selectively removing the insulating layer, so as to expose the wire, forming a first electrode on the insulating layer in the emissive area, forming an electroluminous layer on the first electrode, and forming a second electrode on the electroluminous layer and the wire.
