    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.

    Abstract: A display unit includes a display panel and a first protective sheet. The display panel has a light-emitting surface. The first protective sheet is provided on the light-emitting surface. The first protective sheet provided in the display unit includes a first impact dispersion layer, a first strain relaxation layer, and a gel-like first impact absorption layer. The first impact dispersion layer has a pencil hardness of 3H or higher. The first strain relaxation layer has flexural strength and tensile strength both higher than the flexural strength and the tensile strength of the first impact dispersion layer. The gel-like first impact absorption layer has a thickness of a submillimeter order or more. The first impact absorption layer, the first strain relaxation layer, and the first impact dispersion layer are arranged in this order from the light-emitting surface.

    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: Provided is a display (1) including: an insulating layer (19) having an opening (19M); and a light-emission device (10) including a functional layer (15) and provided in the opening of the insulating layer, the functional layer being provided between a first electrode (14) and a second electrode (16) and including a light emitting layer. The insulating layer includes a low-refractive-index layer, the low-refractive-index layer being made of a material having a lower refractive index than a refractive index of a layer (15A), and the layer (15A) being in proximity to the insulating layer and included in the functional layer.
