Abstract
Provided is a reflective anode for an organic EL display device having a reflective film made from an Al-based alloy which can realize a low contact resistance with an oxide conductive film and achieve an excellent reflectivity. Provided is also a method for manufacturing the reflective anode for an organic EL display device. The method includes: a step of forming an Al-based alloy film containing 0.1 to 2 atomic % of Ni or Co on a substrate; a step of subjecting the Al-based alloy film to a thermal treatment in a vacuum or an inactive gas atmosphere at the temperature of 150 degrees C. or above; and a step of forming an oxide conductive film so as to be in direct contact with the Al-based alloy film.
