Abstract:
1. A display device in which an Al alloy film and a conductive oxide film are directly connected without interposition of refractory metal, wherein the Al alloy film comprises 0.1 to 6 at % of at least one element selected from the group consisting of Ni, Ag, Zn, Cu, and Ge, 0.1 to 2 at % of Mg, and at least one element selected from the group consisting of Cr, Mn, Ru, Rh, Pd, Ir, Pt, La, Ce, Pr, Gd, Tb, Sm, Eu, Ho, Er, Tm, Yb, Lu, and Dy as alloy components, and wherein the at least one element selected from the group consisting of Ni, Ag, Zn, Cu, and Ge are concentrated at an interface of contact between the Al alloy film and the conductive oxide film in a layer having a thickness of from 1 to 5 nm.
