Abstract: The display device includes a display circuit layer having a hollow at a middle area, a front film overlapping a first area, a resin layer, a first back film overlapping the first area and stuck to a back surface of a resin substrate so as to protrude from the hollow at a boundary between the first area and the middle area, and a second back film overlapping the second area and stuck to the back surface of the resin substrate so as to protrude from the hollow at a boundary between the second area and the middle area. The display circuit layer includes an inorganic insulating layer which has the hollow. The first back film and the second back film are separated by the middle area in the first direction.

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.
