Abstract

Provided is a display apparatus including a display panel that is capable of being rolled up, and a protection member, the protection member including a back surface portion layered closer to a back surface of the display panel, a first folded portion folded toward a front surface of the display panel from one end of the back surface portion in an orthogonal direction orthogonal to a roll-up direction in which the display panel is rolled up, and a second folded portion folded toward the front surface from another end of the back surface portion in the orthogonal direction. In the display apparatus, the first folded portion includes a first front surface portion arranged at one end of the front surface in the orthogonal direction, and the second folded portion includes a second front surface portion arranged at another end of the front surface in the orthogonal direction.

Claims (18)

1. A display apparatus comprising:

a display panel that is capable of being rolled up; and

a protection member including a back surface portion layered closer to a back surface of the display panel, a first folded portion folded toward a front surface of the display panel from one end of the back surface portion in an orthogonal direction orthogonal to a roll-up direction in which the display panel is rolled up, and a second folded portion folded toward the front surface from another end of the back surface portion in the orthogonal direction, wherein

the first folded portion includes a first front surface portion arranged at one end of the front surface in the orthogonal direction,

the second folded portion includes a second front surface portion arranged at another end of the front surface in the orthogonal direction, and

the protection member is made of at least one of a foam material or a cloth material.

2. The display apparatus according to claim 1 , wherein

each of the first front surface portion and the second front surface portion is arranged along the roll-up direction.

3. The display apparatus according to claim 2 , wherein

each of the first front surface portion and the second front surface portion is arranged from a front end to a back end of the front surface in the roll-up direction.

4. The display apparatus according to claim 1 , wherein

the first folded portion includes a plurality of the first front surface portions lined up in the roll-up direction, and

the second folded portion includes a plurality of the second front surface portions lined up in the roll-up direction.

5. The display apparatus according to claim 1 , wherein

each of a dimension of the first folded portion and a dimension of the second folded portion is smaller than a dimension of the back surface portion in the roll-up direction.

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

a reinforcing member with rigidity higher than rigidity of the display panel, the reinforcing member being arranged between the display panel and the back surface portion.

7. The display apparatus according to claim 1 , wherein the protection member is further made of a film material.
