Abstract
An Ag alloy film used for a reflecting electrode or an interconnection electrode, the Ag alloy film exhibiting low electrical resistivity and high reflectivity and having exceptional oxidation resistance under cleaning treatments such as an Oplasma treatment or UV irradiation, wherein the Ag alloy film contains either In in an amount of larger than 2.0 atomic % to 2.7 atomic % or smaller; or Zn in an amount of larger than 2.0 atomic % to 3.5 atomic % or smaller; or both. The Ag alloy film may further contain Bi in an amount of 0.01 to 1.0 atomic %.
