摘要： Disclosed is a reflective anode electrode for an organic EL display, which comprises a novel Al-based alloy reflective film. The reflective anode electrode is capable of assuring low contact resistance and high reflectance even in cases where the Al reflective film is in direct contact with an oxide conductive film such as an ITO or IZO film.
