Abstract: A manufacturing substrate, on which a lamination is formed, is disposed on a first substrate. The lamination includes a first sheet substrate having flexibility and adhered to the first substrate, an organic layer that emits light such that brightness is controlled in each of a plurality of pixels forming an image in a display area, and a sealing layer. A light blocking area that does not overlap the display area in a plan view is formed on the first substrate, and after the first substrate is irradiated with light on a side that opposite to the sheet substrate, the first substrate is delaminated from the first sheet substrate.
