Abstract

Disclosed is a display device comprising a display panel, and a support layer disposed under the display panel. The display panel includes a display area that displays an image in a bending area and in a non-bending area, and a non-display area disposed adjacent to the display area in the bending area and the non-bending area. The display device is bend in the bending area during a sliding motion and not bent in the non-bending area adjacent to the bending area during the sliding motion. The non-display area that is disposed the bending area includes pattern areas and non-pattern areas adjacent to the pattern areas. Each of the pattern areas includes a concave portion and a remaining portion.

First claim

What is claimed is:

1. A display device comprising:
a display panel including a display area that displays an image and a non-display area adjacent to the display area; and
a support layer disposed under the display panel, wherein
the display device is wound about a central axis that is parallel to a first direction,
the non-display area includes:
pattern areas; and
non-pattern areas adjacent to the pattern areas,

each of the pattern areas includes:
a concave portion; and
a remaining portion,

a first width of the remaining portion of at least one of the pattern areas in the first direction is smaller than a second width of at least one of the non-pattern areas in the first direction, and
the first width of the remaining portion of the at least one of the pattern areas in the first direction is different than a third width of another remaining portion of the at least one of the pattern areas in the first direction.

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

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

4. The display device of claim 1 , further comprising:
a window disposed over the display panel.

5. The display device of claim 4 , wherein
the window includes:
a light transmitting area corresponding to the display area; and
a bezel area corresponding to the non-display area, and the bezel area overlaps the concave portion of at least one of the pattern areas.

6. The display device of claim 4 , wherein
the window includes:
a light transmitting area corresponding to the display area; and
a bezel area corresponding to the non-display area, and the bezel area does not overlap the concave portion of at least one of the pattern areas.

7. The display device of claim 1 , wherein
the support layer includes support bars that extend in the first direction and that are spaced apart from each other in a second direction intersecting the first direction, and
the display device is wound in the second direction.

8. The display device of claim 7 , 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.

9. The display device of claim 1 , wherein the concave portion of each of the patterned area includes an opening oriented in the first direction.

10. The display device of claim 1 , wherein the display device configured to be wound multiple times about the central axis that is parallel to the first direction.

11. The display device of claim 1 , further comprising:
a roller extending in the first direction, a center portion of the roller defining the central axis, wherein
the display device is configured to be wound about the roller multiple times.

12. A display device comprising:
a display panel including a display area that displays an image and a non-display area adjacent to the display area; and
a support layer disposed under the display panel, wherein
the display device is wound about a central axis that is parallel to a first direction,
the non-display area includes:
pattern areas; and
non-pattern areas adjacent to the pattern areas,

each of the pattern areas includes:
a concave portion; and
a remaining portion,

a first width of the remaining portion of at least one of the pattern areas in the first direction is smaller than a second width of at least one of the non-pattern areas in the first direction, and
the first width of the remaining portion of the at least one of the pattern areas decreases as a distance between the remaining portion of the at least one of the pattern areas and the central axis increases.

13. An electronic device comprising:
a display panel including a display area that displays an image and a non-display area adjacent to the display area; and
a support layer disposed under the displav panel, wherein
the display device is wound about a central axis that is parallel to a first direction,
the non-display area includes:
pattern areas; and
non-pattern areas adjacent to the pattern areas,

each of the pattern areas includes:
a concave portion; and
a remaining portion,

a first width of the remaining portion of at least one of the pattern areas in the first direction is smaller than a second width of at least one of the non-pattern areas in the first direction,
the flexible display device is wound in a second direction intersecting the first direction, and
a distance in the second direction between two non-pattern areas adjacent to each other among the non-pattern areas increases as a distance between the two non-pattern areas adjacent to each other among the non-pattern areas and the central axis increases.
