Abstract: A display device includes a first insulating substrate, a second insulating substrate, and a sealant. The first insulating substrate flexible and has a display area provided with an image display function. The second insulating substrate is smaller than the first insulating substrate and covers the display area. The sealant is disposed around the display area and fixes the first insulating substrate and the second insulating substrate together. The first insulating substrate has a bent portion that is adjacent to an edge of the second insulating substrate and a return portion that is folded back away from the second insulating substrate.

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.
