Mask, Method for Manufacturing Mask, Method for Manufacturing Display Device, and Display Device

A method for manufacturing a display device, comprising:

• a formation step of irradiating a curable resin film formed on a base material with laser light from the base material side to remove the curable resin film in the irradiated area, thereby forming individualized pieces of a predetermined shape composed of the curable resin film with a reaction rate of 25% or less on the base material;
• a transfer step of transferring the individualized pieces of the predetermined shape to a predetermined position on a wiring substrate or to an electrode surface of a light-emitting element;
• and
• a mounting step of mounting the light-emitting element to the wiring substrate via the transferred individualized pieces.

A display device, comprising:

• a plurality of light-emitting elements;
• a wiring substrate on which the light-emitting elements are arranged;
• and
• a cured film that connects the plurality of light-emitting elements to the wiring substrate, wherein
• the cured film is made by curing individualized pieces of a predetermined shape composed of a curable resin film, and
• the predetermined shape is at least one selected from a polygon with obtuse angles, a polygon with rounded corners, an ellipse, an oval, and a circle.
