Abstract: A display panel including a metal film, an adhesive layer disposed on the metal film, a first resin substrate disposed on the adhesive layer, light-emitting elements disposed above the first resin substrate, and a second resin substrate disposed above the light-emitting elements. The adhesive layer includes contact portions in contact with the metal film and gaps are present between the contact portions where the adhesive layer is not in contact with the metal film.

Abstract: A display device includes a flexible substrate, a display device layer, a polarizing plate, and a warpage suppressing member. The flexible substrate has a front surface on a front surface side and a back surface on a back surface side. The display device layer is provided on the front surface side of the flexible substrate and includes a self-luminescent element. The polarizing plate is opposed to the flexible substrate across the display device layer and has a predetermined dimensional change characteristic corresponding to environmental change. The warpage suppressing member is provided on the back surface side of the flexible substrate and has a dimensional change characteristic of the same tendency as the dimensional change characteristic of the polarizing plate. The warpage suppressing member is configured to cancel at least a portion of warping stress of the polarizing plate to be applied to the flexible substrate.
