Abstract:
1. A vapor deposition device that forms a coating film having a predetermined pattern on a substrate the vapor deposition device comprising: a vapor deposition unit including a vapor deposition source having at least one vapor deposition source opening, a vapor deposition mask disposed between the at least one vapor deposition source opening and the substrate, and a limiting unit that is disposed between the at least one vapor deposition source opening and the vapor deposition mask and in which a plurality of limiting portions are disposed along a first direction that is orthogonal to a normal line direction of the substrate; and a moving mechanism that moves one of the substrate and the vapor deposition unit relative to the other along a second direction that is orthogonal to the normal line direction of the substrate and the first direction, in a state in which the substrate and the vapor deposition mask are spaced apart at a fixed spacing, wherein the coating film is formed by causing vapor deposition particles discharged from the at least one vapor deposition source opening and passing through a plurality of limiting openings separated by the plurality of limiting portions and a plurality of mask openings formed in the vapor deposition mask to adhere onto the substrate, the limiting unit includes a plurality of plate members that are stacked on one another, the plurality of plate members are stacked in the normal line direction of the substrate, a plurality of through holes constituting the plurality of limiting openings are formed in each of the plurality of plate members, the plurality of through holes formed in each of the plurality of plate members include a plurality of types of through holes having different opening widths, and the plurality of types of through holes having different opening widths are in communication in the normal line direction of the substrate to constitute the plurality of limiting openings.
