Abstract: A blue fluorescent light-emitting layer is provided in common for first and second subpixels, a green fluorescent light-emitting layer is provided in common for second and third subpixels, and a red light-emitting layer is provided in common for the second and fourth subpixels. In the second subpixel, an opposing surface distance is less than or equal to a Förster radius, and at least of the blue fluorescent light-emitting layer and the green fluorescent light-emitting layer are layered with the red light-emitting layer with a separation layer interposed therebetween.

Abstract: In this manufacturing method, in a blue fluorescent light-emitting layer formation step, a blue fluorescent light-emitting layer is formed in both a subpixel and a subpixel; in a green fluorescent light-emitting layer formation step, a green fluorescent light-emitting layer is formed in both the subpixel and a subpixel; and in a red light-emitting layer formation step, a red light-emitting layer is formed in both the subpixel and a subpixel. In at least two of the abovementioned steps, linear vapor deposition is performed using a slitted mask having an opening that is provided so as to extend across a plurality of pixels.

Abstract: An organic EL display device with higher resolution, suppressed power consumption while being driven and low manufacturing cost, and no color mixing and color shifting between subpixels adjacent to each other is provided. In a B subpixel, a first separation layer is provided between a common blue-light-emitting layer and a common green-light-emitting layer. In a G subpixel, a second separation layer is provided between the common green-light-emitting layer and a common red-light-emitting layer.
