Abstract
A display device and a method for production thereof. The display device comprises a substrate, thin film transistors and a transparent conductive film which are formed on the substrate, and an aluminum alloy film which electrically connects the thin film transistors to the transparent conductive film, such that there exists an oxide film of said aluminum alloy at the interface between said aluminum alloy film and said transparent conductive film, said oxide film having a thickness of 1 to 10 nm and containing oxygen in an amount no more than 44 atom %. The display device has the aluminum alloy film and the transparent conducive film in direct contact with each other, obviating the necessity of barrier metal between them.
