4. The display device of claim 1 , wherein

a thickness of the second layer is 90 μm to 150 μm.

5. The display device of claim 1 , wherein

thicknesses of the first layer and the third layer are the same, and

a thickness of each of the first layer and the third layer is 30 μm to 40 μm.

6. The display device of claim 1 , wherein

a thickness of the plate is 150 μm to 250 μm.

7. The display device of claim 1 , wherein

the first layer to the third layer include a plurality of carbon fibers,

a longitudinal direction of a first carbon fiber included in the first layer and the third layer is parallel to a first direction, and

a longitudinal direction of a second carbon fiber included in the second layer is parallel to a second direction.

8. The display device of claim 7 , wherein

the display device is folded based on a folding axis, and

the folding axis is parallel to the first direction.

9. The display device of claim 8 , wherein

the plate includes a folding area that overlaps the folding axis and a folding peripheral area that does not overlap the folding axis, and

the plate has a plurality of grooves positioned in the folding area.

10. The display device of claim 7 , wherein

an elastic modulus of the plate in the first direction is greater than that in the second direction.

11. A display device comprising:

a display module that is foldable with respect to a folding axis; and

a plate positioned on a rear surface of the display module,

the first layer to the third layer include a plurality of first carbon fibers,

a longitudinal direction of the first carbon fibers is parallel to the first direction,

the second layer includes a plurality of second carbon fibers, and

a longitudinal direction of the second carbon fibers is parallel to a second direction.

18. The display device of claim 17 , wherein

the folding axis is parallel to the first direction.

19. The display device of claim 18 , wherein

the plate includes a folding area that overlaps the folding axis and a folding peripheral area that does not overlap the folding axis, and

the plate has a plurality of grooves positioned in the folding area.

20. The display device of claim 17 , further comprising

a digitizer positioned on a rear surface of the plate.
