ABSTRACT:
The present invention provides a display device substrate includes a first wiring layer formed on a substrate made of an insulating material, a second wiring layer formed to cross the first wiring layer, and an insulating film interposed between the first and second wiring layers at a cross point portion therebetween, wherein the first wiring layer is constituted by an electrode wiring layer made of a material containing aluminum as a main component and a surface covering layer formed by causing a refractory metal to denature the electrode wiring layer. The present invention also provides a method of manufacturing a display device substrate in which an electrode wiring layer made of a material containing aluminum as a main component is formed on a substrate made of an insulating material, a thin film made of a refractory metal is formed on the electrode wiring layer, and heat treatment is performed to cause the refractory metal to denature a surface portion of the electrode wiring layer, thereby forming a surface covering layer.
