Abstract

A display device includes: a display panel comprising a display area including a plurality of pixels and a non-display area disposed around the display area; and a plurality of flexible printed circuit boards disposed in the non-display area along a first edge of the display panel, where distances of a first end portion of each of the flexible printed circuit boards from the first edge are different from each other.

First claim

What is claimed is:

1 . A display device comprising:
a display panel comprising a display area including a plurality of pixels and a non-display area disposed around the display area; and a plurality of flexible printed circuit boards disposed in the non-display area along a first edge of the display panel, wherein distances of a first end portion of each of the flexible printed circuit boards from the first edge are different from each other.

2 . The display device of claim 1 , wherein
the first edge is parallel to a first direction, and the display panel is curved around an axis in a second direction which is perpendicular to the first direction.

3 . The display device of claim 2 , wherein
the display panel includes a second edge and a third edge, which are connected to the first edge and opposite to each other in the first direction, the flexible printed circuit boards include a first flexible printed circuit board disposed at a center of the display panel and a second flexible printed circuit board disposed adjacent to the second edge of the display panel, and a first distance between the first end portion of the first flexible printed circuit board and the first edge is greater than a second distance between the first end portion of the second flexible printed circuit board and the first edge.

4 . The display device of claim 3 , wherein
the flexible printed circuit boards further include a third flexible printed circuit board and a fourth flexible printed circuit board, which are disposed between the first flexible printed circuit board and the second flexible printed circuit board, the third flexible printed circuit board is disposed closer to the first flexible printed circuit board than to the second flexible printed circuit board, the fourth flexible printed circuit board is disposed closer to the second flexible printed circuit board than to the first flexible printed circuit board, and a third distance between the first end portion of the third flexible printed circuit board and the first edge is smaller than a fourth distance between the first end portion of the fourth flexible printed circuit board and the first edge.

5 . The display device of claim 4 , wherein
the first distance is greater than the third distance, and the second distance is smaller than the fourth distance.

6 . The display device of claim 2 , further comprising:
a plurality of first pad portions disposed in the display panel; and a plurality of second pad portions disposed in each of the flexible printed circuit boards, wherein the first pad portions are in contact with the second pad portions.

7 . The display device of claim 6 , wherein
the display panel includes a second edge and a third edge, which are connected to the first edge and opposite to each other in the first direction, and distances of each of the second pad portions from the first end portion are different from each other.

8 . The display device of claim 7 , wherein
the second pad portions are disposed to be farther away from the first end portions as being closer to the second edge or the third edge from a center of the display panel in the first direction.

9 . A display device comprising:
a display panel comprising a display area including a plurality of pixels and a non-display area disposed around the display area; a plurality of flexible printed circuit boards disposed in the non-display area along a first edge of the display panel; a plurality of first pad portions disposed in the display panel; and a plurality of second pad portions disposed in each of the flexible printed circuit boards, wherein distances of a first end portions of each of the flexible printed circuit boards from the first edge are different from each other, and distances of each of the second pad portions from the first end portion are different from each other.

10 . The display device of claim 9 , wherein
the first edge is parallel to a first direction, and the display panel is curved around an axis in a second direction which is perpendicular to the first direction.

11 . The display device of claim 10 , wherein
the first pad portions are in contact with the second pad portions.

12 . The display device of claim 11 , wherein
the display panel includes a second edge and a third edge, which are connected to the first edge and opposite to each other in the first direction, and the second pad portions are disposed to be farther away from the first end portions as being closer to the second edge or the third edge from a center of the display panel in the first direction.

13 . The display device of claim 10 , wherein
the flexible printed circuit boards include a first flexible printed circuit board disposed at a center of the display panel and a second flexible printed circuit board disposed adjacent to a second edge of the display panel, and a first distance between the first end portion of the first flexible printed circuit board and the first edge is greater than a second distance between the first end portion of the second flexible printed circuit board and the first edge.

14 . The display device of claim 13 , wherein
the flexible printed circuit boards further include a third flexible printed circuit board and a fourth flexible printed circuit board, which are disposed between the first flexible printed circuit board and the second flexible printed circuit board, the third flexible printed circuit board is disposed closer to the first flexible printed circuit board than the second flexible printed circuit board is, the fourth flexible printed circuit board is disposed closer to the second flexible printed circuit board than the first flexible printed circuit board is, and a third distance between the first end portion of the third flexible printed circuit board and the first edge is greater than a fourth distance between the first end portion of the fourth flexible printed circuit board and the first edge.

15 . The display device of claim 14 , wherein
the first distance is greater than the third distance, and the second distance is smaller than the fourth distance.

16 . A display device comprising:
a display panel comprising a display area including a plurality of pixels and a non-display area disposed around the display area, wherein the display panel includes a first edge which is parallel to a first direction, and a second edge and a third edge which are connected to the first edge and opposite to each other in the first direction; a plurality of flexible printed circuit boards disposed in the non-display area along the first edge of the display panel; a plurality of first pad portions disposed in the display panel; and a plurality of second pad portions disposed in each of the flexible printed circuit boards and connected to the first pad portions, wherein the second pad portions are disposed to be farther away from a first end portion of each of the flexible printed circuit boards as being closer to the second edge or the third edge from a center of the display panel in the first direction.

17 . The display device of claim 16 , wherein
the first edge is parallel to a first direction, and the display panel is curved around an axis in a second direction which is perpendicular to the first direction.

18 . The display device of claim 17 , wherein
the first pad portions are in contact with the second pad portions.

19 . The display device of claim 18 , wherein
the flexible printed circuit boards i
