Organic EL display device and organic EL display device manufacturing method

An organic electro luminescence (EL) display device comprising:

• a plurality of pixels each including:
• a first subpixel;
• a second subpixel;
• and
• a third subpixel,
• the first, second, and third subpixels being configured to emit light with peak wavelengths different from each other, and
• the first, second, and third subpixels each including:
• a positive electrode;
• a negative electrode;
• and
• a light-emitting layer formed between the positive electrode and the negative electrode,
• wherein either of the positive electrode and the negative electrode is a reflective electrode or includes a reflective layer, and another of the positive electrode and the negative electrode is a transparent electrode or a translucent electrode configured to transmit the light with peak wavelengths different from each other,
• the light-emitting layer is a layered film including:
• a first fluorescence light-emitting layer configured to emit light with a longest peak wavelength;
• a second fluorescence light-emitting layer configured to emit light with a shortest peak wavelength;
• and
• a third fluorescence light-emitting layer configured to emit light with a peak wavelength between the longest peak wavelength of the first fluorescence light-emitting layer and the shortest peak wavelength of the second fluorescence light-emitting layer,
• the first fluorescence light-emitting layer, the second fluorescence light-emitting layer, and the third fluorescence light-emitting layer are each formed as a single common layer in the plurality of pixels,
• the first fluorescence light-emitting layer is arranged above or below the second fluorescence light-emitting layer and the third fluorescence light-emitting layer,
• in the first subpixel, a first separation layer without including a light-emitting material is provided between the second fluorescence light-emitting layer and the third fluorescence light-emitting layer, and
• in the second subpixel, a second separation layer without containing a light-emitting material is provided between the first fluorescence light-emitting layer and a fluorescence light-emitting layer lying adjacent to the first fluorescence light-emitting layer.
