A vapor deposition mask used to manufacture a display device includes a notch portion. The vapor deposition mask is provided with an FMM sheet and a first cover sheet. The first cover sheet includes a trunk portion and a notch forming portion that protrudes from the trunk portion and prevents film formation on the notch portion, and the thickness of at least a part of the notch forming portion is smaller than the thickness of the trunk portion.

Vapor deposition mask and vapor deposition device

A film thickness securing region of a green island-shaped hole transport layer in a display device is located at the inside of a green pixel light-emitting region in a direction in which a red pixel and a green pixel are adjacent to each other, and part of a shadow region of a red island-shaped hole transport layer and part of a shadow region of the green island-shaped hole transport layer overlaps each other within the green pixel light-emitting region.

Display device and method for manufacturing same

A first region of a valid portion formed on a mask sheet has a shape corresponding to a shape of each of active regions and provided for each active region of a vapor target substrate. A second region of the valid portion is located outside of the first region, and includes a plurality of vapor deposition holes (H) covered with a hauling sheet.
