- the magnetic plate 150 can be attracted in a region where the metal part of the vapor deposition mask and the magnetic plate 150 overlap in the thickness direction (region overlapped in the thickness direction with the region indicated by reference sign X in FIG. 2).
- a region that overlaps only with the resin mask 20 made of a resin material cannot be attracted by the magnetic plate 150. Therefore, in a region that cannot be attracted to the magnetic plate 150, that is, in a portion where the slit 15 of the metal mask 10 and the deposition target 200 overlap in the thickness direction, there is a gap between the deposition mask 100 and the deposition target 200. It tends to occur.
- a gap is generated between the vapor deposition mask 100 and the vapor deposition object 200 at a position overlapping the region of the vapor deposition mask 100 that cannot be attracted by the magnetic plate 150 in the thickness direction.

Generation of a gap between the object 200 and the object 200 can be suppressed.
- FIG. 1B is a schematic cross-sectional view showing a state in which the deposition object 200 is pushed by the pushing member 130.
- the cross-sectional shape in the thickness direction of the vapor deposition object 200 at the portion pushed by the push member 130 is trapezoidal, but the material of the vapor deposition object 200 and the push member 130,

Adhesion between the vapor deposition mask 100 and the vapor deposition object when the 100 and the magnetic plate 150 are attracted can be increased. However, even in the vapor deposition mask 100 made of only a metal material, the vapor deposition mask 100 and the magnetic plate 150 may not be sufficiently attracted depending on the ratio of the metal portion or the metal material. This is because a gap may be formed between the object 200 and the object 200.
- the method for forming a vapor deposition pattern according to an embodiment is suitable when the vapor deposition mask 100 in which a resin material is included in its constituent members is used. Specifically, when the vapor deposition mask 100 and the magnetic plate 150 are attracted, the vapor deposition mask 100 having a region that cannot be attracted to the magnetic plate 150, that is, the vapor deposition mask 100 made of only a resin material, as described above.

Among them, the resin material is preferable in that the vapor deposition object in contact with the pressing member 130 can be uniformly pressed and a sufficient pressing effect can be obtained as compared with the metal material.
- a resin material a polyimide resin etc. can be mentioned, for example.
- the shape of the pushing member 130 on the side in contact with the vapor deposition object 200 may be an R shape, in other words, the shape on the side of the pushing member 130 may have a curvature (not shown).
- a curvature there is no restriction

- the area of the portion where one pushing member 130 is in contact with the vapor deposition object 200 in contact with the one pushing member 130 is preferably 200 mm 2 or more.

- the magnetic plate 150 can be arranged so that the metal portion of the vapor deposition mask and the frame portion of the metal frame overlap the effective portion of the magnetic plate 150 in the thickness direction.
- the magnetic plate is disposed so that the metal portion of the vapor deposition mask or the frame portion of the metal frame and the effective portion of the magnetic plate 150 overlap in the thickness direction.
