Display apparatus

1. A display apparatus, comprising:

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, wherein

ends of the protection sheet are bent from the back surface to the display surface of the display panel,

the protection sheet is formed from nylon fibers, and

angles between a longitudinal direction of the nylon fibers and edges of the display surface are set such that the nylon fibers are elongated in directions parallel to the edges of the display surface in a state in which the display panel and the protection sheet are rolled up.

2. The display apparatus according to claim 1 , wherein the woven fabric contains synthetic fibers.

3. The display apparatus according to claim 1 , wherein the display surface has a rectangular shape, and

the angles between the longitudinal direction of the nylon fibers contained in the woven fabric and the edges of the display surface are equal to or greater than 30° but equal to or smaller than 60°.

4. The display apparatus according to claim 3 , wherein the angles between the longitudinal directions of the nylon fibers contained in the woven fabric and the edges of the display surface are equal to or greater than 40° but equal to or smaller than 50°.

5. The display apparatus according to claim 1 , further comprising

an adhesive member arranged between the display panel and the protection sheet, the adhesive member bonding the display panel and the protection sheet.

6. The display apparatus according to claim 5 , further comprising a core which rolls up the display panel and the protection sheet placed above the display panel.

7. The display apparatus according to claim 6 , wherein

the core has a main body and a through portion that penetrates the main body in a radial direction of the main body, and

the through portion receives a portion of a flexible board connected to the display panel.

8. The display apparatus according to claim 1 , further comprising

a plate-shaped member arranged between the display panel and the protection sheet.

9. The display apparatus according to claim 8 , wherein the plate-shaped member is formed from stainless steel.

10. The display apparatus according to claim 1 , wherein, in a rolled up state of the protection sheet, an amount of elongation of the nylon fibers is different at each position of the protection sheet in a direction equal to or greater than 30° and equal to or smaller than 60° with respect to the longitudinal direction of the nylon fibers.

11. The display apparatus according to claim 1 , further comprising:

a first support member attached to the protection sheet;

a second support member opposed to the first support member; and

a first arm portion and a second arm portion, wherein

the first arm portion and the second arm portion connect the first support member to the second support member, and

the first arm portion and the second arm portion are configured to apply a force in a direction in which the first support member is separated from the second support member.
