Organic el display panel and method of manufacturing organic el display panel

An organic EL (Electro Luminescence) display panel having a plurality of pixel electrodes arranged in a matrix pattern on a substrate, with a light emitting layer disposed on each of the pixel electrodes, the light emitting layer containing an organic light emitting material, the organic EL display panel comprising:

• the substrate;
• the plurality of pixel electrodes disposed in a matrix pattern over the substrate;
• a first current feeding auxiliary electrode layer disposed to extend in a column or row direction in at least one of gaps between adjacent ones of the pixel electrodes over the substrate;
• a second current feeding auxiliary electrode layer that contains aluminum as a main constituent and is disposed to be superposed on the first current feeding auxiliary electrode layer;
• a plurality of light emitting layers disposed on the plurality of pixel electrodes;
• and
• a common electrode layer disposed continuously to cover the first current feeding auxiliary electrode layer and the second current feeding auxiliary electrode layer as well as an upper side of the plurality of light emitting layers,
• wherein the first current feeding auxiliary electrode layer and the common electrode layer make contact with each other at least in a partial area on a wall surface perpendicular to an upper surface of the first current feeding auxiliary electrode layer, and
• the first current feeding auxiliary electrode layer is composed of a material that contains a metal different from aluminum as a main constituent and is lower than aluminum in contact resistance in air.
