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.
