Patent ID: 8569774

Claim:
An organic electroluminescence (EL) display panel, comprising: a substrate; a thin-film transistor layer formed on the substrate; an interlayer insulating film formed above the thin-film transistor layer; a plurality of strip-shaped barrier ribs arranged in parallel on the interlayer insulating film; a plurality of first electrode groups, each electrode group of the plurality of first electrode groups comprising first electrodes arranged in a line and between two adjacent barrier ribs of the plurality of strip-shaped barrier ribs, each electrode 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 each formed to cover a different electrode of the plurality of first electrode groups; and a second electrode formed above the plurality of light-emitting layers, wherein each electrode of the first electrodes is formed such that: at least one of end portions of the first electrodes in a parallel direction with respect to the barrier ribs comprises 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 comprises a two-film portion in which the transparent conductive film is layered on the reflective metal film, and a metal oxide film is at least partially formed on an entire surface of the single-film portion of each electrode of the first electrodes by partially oxidizing the metal material of which the reflective metal film is formed.
