Abstract
A display device is provided with a Cu alloy film having high adhesiveness to a transparent substrate and a low electrical resistivity. The Cu alloy film for the display device is directly brought into contact with the transparent substrate, and the Cu alloy film has the multilayer structure, which includes a first layer (Y) composed of a Cu alloy containing, in total, 2-20 atm % of at least one element selected from among a group composed of Zn, Ni, Ti, Al, Mg, Ca, W, Nb, and Mn, and a second layer (X) which is composed of pure Cu or substantially a Cu alloy having Cu as the main component and has an electrical resistivity lower than that of the first layer (Y). The first layer (Y) is brought into contact with the transparent substrate.
