Abstract: A method of manufacturing a flexible device includes joining a first surface of a support substrate to a back surface of a flexible substrate, the first surface being opposite to a second surface of the support substrate; forming an element layer on a front surface of the flexible substrate; and performing multidirectional oblique irradiation of an interface and its vicinity between the support substrate and the flexible substrate with laser light from the second surface of the support substrate to detach the support substrate from the flexible substrate.

Abstract: A light-emitting display device includes an element-formation substrate and a plurality of pixels. The element-formation substrate includes a first barrier film and a second barrier film provided on a substrate, the first barrier film and the second barrier film being provided in the stated order from the substrate and suppressing ingress of moisture. The plurality of pixels is provided on the element-formation substrate. The element-formation substrate further includes an organic part that fills a crack occurred in the first barrier film, or that is attached around a part of a metallic foreign substance protruding from the first barrier film.
