An organic electroluminescence (EL) display panel and method of manufacturing an organic EL display panel. The display panel includes a substrate on which a thin-film transistor layer is formed, with an interlayer insulating film formed above the thin-film transistor layer. A plurality of strip-shaped barrier ribs are arranged in parallel on the interlayer insulating film. Each electrode of a plurality of first electrode groups has first electrodes arranged in a line and arranged between two adjacent barrier ribs of the plurality of strip-shaped barrier ribs, with each of the first electrodes including a transparent conductive film and a reflective metal film formed of a metal material. A plurality of light-emitting layers are each formed to cover a different electrode of the plurality of first electrode groups, while a second electrode is formed above the plurality of light-emitting layers. Each electrode of the plurality of first electrode groups is formed such that an end portion of the first electrode in a parallel direction with respect to the barrier ribs includes a single-film portion in which the transparent conductive film is not formed, and a portion of the first electrode other than the single-film portion includes a two-film portion in which the transparent conductive film is layered on the reflective metal film. A metal oxide film is formed on an entire surface of the single-film portion of each first electrode by partially oxidizing the metal material. |
