Abstract
A wire substrate, a display device including a wire substrate, and a method of fabricating a wire substrate are disclosed. The display device comprises: a first base; and a first wiring layer disposed on the first base and comprising a conductive layer and a metal oxide layer stacked on the conductive layer, wherein the metal oxide layer comprises molybdenum (Mo), tantalum (Ta), and oxygen (O). The conductive layer includes a first metal layer on the first base, and a second metal layer between the first metal layer and the metal oxide layer. The second metal layer has a higher electrical conductivity than the first metal layer, and a thickness of the second metal layer is greater than a thickness of the first metal layer.
