Patent ID: 8044399

Claim:
A display comprising a glass substrate provided with a transparent conducting film, thin-film transistors, and an aluminum alloy wiring film electrically connecting the thin-film transistors to the transparent conducting film; wherein the aluminum alloy wiring film is a layered structure having a first layer (X) of an aluminum alloy comprising at least one element selected from the element group Q consisting of Ni, Ag, Zn and Cu in a content in the range of 0.1 to 6 at. %, and at least one element selected from the element group R consisting of rare-earth elements, Mg, Mn, V, Pt, Cr, Ru, Rh, Pd, Ir, W, Ti, Zr, Nb, Hf, Ta, Sn and Fe in a content in the range of 0.1 to 6 at. %, and a second layer (Y) of pure aluminum or an aluminum alloy containing aluminum as a principal component and having a resistivity lower than that of the first layer (X), and the first layer (X) is in direct contact with the transparent conducting film.
