Abstract: A manufacturing method including: forming a first electrode; forming a first bank; forming a first organic functional film; forming a second bank; forming a second organic functional film; and forming a second electrode. In the forming of the second bank, the second bank is formed such that, in plan view, a bottom edge of a sidewall surface of the second bank facing the second aperture is located at the same position as or is set back from a bottom edge of a sidewall surface of the first bank facing the first aperture. In the forming of the second organic functional film, the droplet of the second ink is applied such that an upper edge of the second organic functional film within the second aperture is located at a same level as or at a higher level than the bottom edge of the sidewall surface of the second bank.
