A display device includes a display panel capable of being rolled up or folded and a cover member that is placed upon the display panel and that is capable of being rolled up or folded together with the display panel. A thermal shrinkage rate of the cover member in a bending direction along which the display panel is bent when the display panel is rolled up is smaller than a thermal shrinkage rate of the cover member in a perpendicular direction that is perpendicular to the bending direction, or a thermal shrinkage rate of the cover member in a bending direction along which the display panel is bent when the display panel is folded is smaller than a thermal shrinkage rate of the cover member in a perpendicular direction that is perpendicular to the bending direction.

Folded or rolled display device having thermal shrinkage rates

The display panel is a display panel that is flexible, including: an EL structure layer including a plurality of EL elements arranged two-dimensionally; a foamed resin layer on a side of the EL structure layer that is opposite to a light emitting surface of the EL structure layer; a metal layer provided between the EL structure layer and the foamed resin layer; and a first adhesive layer provided between the EL structure layer and the metal layer and comprises an adhesive having an elastic modulus of 90 kPa or more.

Display panel and display device including adhesive layer for increasing impact resistance

A display apparatus includes a display panel that is flexible, the display panel including a display surface and a back surface on a back side of the display surface, and a protection sheet attached to the back surface of the display panel and formed from woven fabric.

Display apparatus

Provided is a display device including a display panel capable of being folded or rolled up, and a plate-shaped member placed on the display panel and capable of being folded or rolled up together with the display panel, the plate-shaped member including a bendable portion that is bent when the plate-shaped member is folded or rolled up together with the display panel, the bendable portion including a region group including a plurality of regions arranged in a bending direction along which the bendable portion is bent when the plate-shaped member is folded or rolled up together with the display panel, the bendable portion having openings with each of the regions having a plurality of through holes formed therein, an opening area ratio of the bendable portion in each of the regions being different from an opening area ratio of the bendable portion in an adjacent one of the regions.
