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 slit mask having an opening that is provided so as to extend across a plurality of pixels.
