摘要： 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.
