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.

Provided is a polarizer having a non-polarization portion with reduced shape unevenness. The polarizer of the present invention is a polarizer having a non-polarization portion, in which the non-polarization portion has a shape matching degree of 0.05 or less. In such polarizer, the number of portions where the shape of the non-polarization portion is distorted is small. Accordingly, when the non-polarization portion of the polarizer is used as, for example, a portion corresponding to a camera portion of an image display apparatus, alignment processability is improved and hence the alignment of the camera can be satisfactorily performed.
