Display device

1. A display device, comprising:

a display module including:

a display area that displays an image in a bending area and in a non-bending area, the bending area being bent when the display device performs a sliding motion and the non-bending area adjacent to the bending area not being bent during the sliding motion; and

a non-display area disposed adjacent to the display area in the bending area and in the non-bending area, wherein the display module includes a display panel outputting the image and an input sensing layer disposed on the display panel; and

a support layer disposed under the display panel, wherein

the non-display area that is disposed in the bending area includes:

pattern areas; and

non-pattern areas disposed adjacent to the pattern areas, and

each of the pattern areas includes:

a concave portion provided in the display panel and the input sensing layer; and

a remaining portion.

2. The display device of claim 1 , wherein

the flexible display device slides about a central axis parallel to a first direction, and

a first width of the remaining portion in the first direction is smaller than or equal to a second width of the non-pattern areas in the first direction.

3. The display device of claim 2 , wherein

the support layer includes support bars extending in the first direction and spaced apart from each other in a second direction intersecting the first direction,

each of the support bars overlaps corresponding one of the non-pattern areas, and

the flexible display device slides in the second direction.

4. The display device of claim 3 , wherein a distance in the second direction between two non-pattern areas adjacent to each other among the non-pattern areas is equal to or smaller than a distance in the second direction between two support bars adjacent to each other among the support bars.

5. The display device of claim 1 , wherein the concave portion of at least one of the pattern areas includes a curved shape.

6. The display device of claim 1 , wherein the concave portion of at least one of the pattern areas includes a polygonal shape.

7. The display device of claim 1 , wherein the concave portion of at least one of the pattern areas is disposed only in the non-display area that is disposed in the bending area.

8. The display device of claim 1 , further comprising:

a window disposed over the display module.

9. The display device of claim 8 , wherein

the window includes:

a light transmitting area corresponding to the display area that is disposed in the bending area and in the non-bending area; and

a bezel area corresponding to the non-display area that is disposed in the bending area and in the non-bending area, and

the bezel area overlaps the concave portion of at least one of the pattern areas.

10. The display device of claim 8 , wherein

the window includes:

a light transmitting area corresponding to the display area that is disposed in the bending area and in the non-bending area; and

a bezel area corresponding to the non-display area that is disposed in the bending area and in the non-bending area, and

the bezel area does not overlap the concave portion of at least one of the pattern areas.

11. The display device of claim 8 , wherein

the pattern areas are not formed in the window, and

a bezel area of the window overlaps the concave portion.

12. The display device of claim 8 , wherein

the concave portion is formed in the window, and

a bezel area of the window does not overlap the concave portion.
