Abstract
A droplet ejection apparatus includes first to fourth droplet ejection heads for ejecting a first liquid material and fifth and sixth droplet ejection heads for ejecting a second liquid material. The first and second droplet ejection heads, the third and fourth droplet ejection heads, and the fifth and sixth droplet ejection heads are arranged along a first direction so that nozzles of the first and second droplet ejection heads, the third and fourth droplet ejection heads, and the fifth and sixth droplet ejection heads are consecutive with a predetermined pitch via a first seam, a second seam and a third seam, respectively, when viewed from a second direction perpendicular to the first direction. The third seam is arranged between the first seam and the second seam when viewed from the second direction.
