Claim:
1. A vapor deposition device for forming a film on a film formation substrate, the vapor deposition device comprising: a vapor deposition source that has an injection hole from which vapor deposition particles are injected; a crucible configured to supply the vapor deposition particles to the vapor deposition source; and an injection controller configured to change a distribution of an injection amount of the vapor deposition particles, wherein: the injection amount of the vapor deposition particles changes depending on an opening width of an overlapping region at which the injection hole and the opening in the deposition preventing plate overlap each other, when viewed from a side of the film formation substrate, the opening in the deposition preventing plate has a rectangular shape, whereas the injection hole has a non-rectangular shape with two short sides that are parallel with each other and two long sides that are curved at a constant distance from each other so that each of the two long sides has a convex shape in a direction parallel to the two short sides, or the injection hole has a rectangular shape, whereas the opening in the deposition preventing plate has a non-rectangular shape with two short sides that are parallel with each other and two long sides that are curved at a constant distance from each other so that each of the two long sides has a convex shape in a direction parallel to the two short sides.
