Organic EL display device and method for manufacturing organic EL display device

An organic EL display device comprising:

• an organic EL layer;
• a reflective electrode including a first reflective film;
• a transparent electrode disposed opposite to the reflective electrode with the organic EL layer interposed between the reflective electrode and the transparent electrode;
• a first protection film disposed on the reflective electrode and arranged between the reflective electrode and the organic EL layer;
• an edge cover of a lattice pattern covering edges of the reflective electrode being aligned in a matrix shape;
• an insulating film on which the reflective electrode is layered;
• a first wiring line disposed on the insulating film;
• and
• a second protection film disposed on the first wiring line and formed in a layer identical to the layer of the first protection film, wherein
• the first protection film includes a frame-shaped portion surrounding a periphery of the organic EL layer in a frame shape, and a thin film portion surrounded by the frame-shaped portion and having a film thickness thinner than a film thickness of the frame-shaped portion,
• the frame-shaped portion is covered by the edge cover,
• a side surface of the edge cover in contact with the organic EL layer and a side surface of the frame-shaped portion in contact with the organic EL layer constitute a continuous plane,
• the reflective electrode includes a first conductive film disposed on an opposite side of the first reflective film to a side on which the organic EL layer is disposed,
• the first wiring line includes a second reflective film formed in a layer identical to the layer of the first reflective film, and a second conductive film formed in a layer identical to the layer of the first conductive film, and
• the second protection film has a film thickness thicker than a film thickness of the second conductive film.
