Abstract
A lamination includes a sheet substrate and a display element layer. The sheet substrate includes a plurality of product regions cut out into a plurality of products and a blank region surrounding the product regions. The display element layer is formed on each of a plurality of display areas placed on each of the plurality of product regions for displaying an image. The sheet substrate adheres to a top of a substrate. The substrate has light transmissivity. A protective film is adhered to the lamination so as to cover the display areas. A divider line is formed in a blank region that surrounds the product regions by removing a portion of the lamination. The substrate is removed from the sheet substrate by irradiating the sheet substrate with a laser beam.
Claims6
A method for manufacturing a display device, comprising:
- a preparing step of preparing a lamination that includes a sheet substrate and a display element layer, the sheet substrate including a plurality of product regions cut out into a plurality of products and a blank region surrounding the product regions, the display element layer formed on each of a plurality of display areas placed on each of the plurality of product regions for displaying an image, the sheet substrate being adhere to a top of a substrate, and the substrate having light transmissivity;
- an adhering step of adhering a protective film on the lamination so as to cover the display areas;
- a dividing step of forming, after the adhering step, a divider line by removing a portion of the blank region of the lamination;
- an irradiating step of irradiating, after the dividing step, the sheet substrate with a laser beam from a side of the substrate that is not in contact with the sheet substrate;
- and
- a removing step of removing the substrate from the sheet substrate after the irradiating step.
