Abstract

A display substrate according to the embodiment includes: a base material having a long direction and a short direction, and including one surface and the other surface, and a first region and a second region; and a hole passing through the one surface and the other surface of the base material, wherein the first region is defined as a folding region in which the one surface is folded to face, the second region is defined as an unfolding region, the hole includes a first hole formed in the first region, and the first hole includes at least three first holes having different sizes in the long direction of the base material.

First claim

What is claimed is:

1 . A display substrate comprising:
a base material foldable based on a folding axis and having a first direction corresponding to the folding axis and a second direction perpendicular to the first direction; and an opening pattern in which at least one of one surface and the other surface of the base material is opened, wherein the base material includes a first side surface and a second side surface positioned in the first direction, wherein the opening pattern comprises: a first pattern part including a first outer pattern spaced apart from the first side at a position closest to the first side surface; a second pattern part provided at a position closer in the second direction from the folding axis than the first pattern part and including a second outer pattern spaced apart from the first side at a position closest to the first side surface; and a third pattern part provided at a position closest in the second direction from the folding axis than the first pattern part and the second pattern part and including a third outer pattern spaced apart from the first side at a position closest to the first side surface, and wherein a distance in the first direction between a first central axis in the first direction of the first outer pattern and a second central axis in the first direction of the second outer pattern is the same as a distance in the first direction between a third central axis in the first direction of the third outer pattern and the second central axis.

2 . The display substrate of claim 1 , wherein a distance in the second direction between the first central axis and the second central axis is the same as a distance in the second direction between the second central axis and the third central axis.

3 . The display substrate of claim 2 , wherein the first pattern part further includes a plurality of first patterns spaced from the first outer pattern along the first direction,
wherein first central axes in the first direction of the plurality of first patterns are aligned in the first direction, and wherein distances in the first direction between the first central axes are the same.

4 . The display substrate of claim 3 , wherein the second pattern part further includes a plurality of second patterns spaced from the second outer pattern along the first direction,
wherein second central axes in the first direction of the plurality of second patterns are aligned in the first direction, and wherein distances in the first direction between the second central axes are the same.

5 . The display substrate of claim 4 , wherein the third pattern part further includes a plurality of third patterns spaced from the third outer pattern along the first direction,
wherein third central axes in the first direction of the plurality of third patterns are aligned in the first direction, and wherein distances in the first direction between the third central axes are the same.

6 . The display substrate of claim 1 , wherein the first to third outer patterns are misaligned in the second direction.

7 . The display substrate of claim 6 , wherein the first outer pattern has a first distance in the first direction from the first central axis to the first side surface,
wherein the second outer pattern has a second distance in the first direction from the second central axis to the first side surface, wherein the third outer pattern has a third distance in the first direction from the third central axis to the first side surface, and wherein the first to third distances are different from each other.

8 . The display substrate of claim 7 , wherein the first distance is greater than each of the second distance and the third distance, and
wherein the second distance is greater than the third distance.

9 . The display substrate of claim 1 , wherein the first pattern part includes an overlapping pattern that overlaps the first outer pattern in the second direction, and
wherein a central axis of the overlapping pattern in the first direction is aligned with the first central axis in the second direction.

10 . The display substrate of claim 1 , wherein the first pattern part includes an overlapping pattern that overlaps the second outer pattern in the second direction, and
wherein a central axis of the overlapping pattern in the first direction is aligned with the second central axis in the second direction.

11 . The display substrate of claim 5 , wherein widths of the first patterns, the second patterns, and the third patterns in the second direction are the same.

12 . The display substrate of claim 1 , wherein the third pattern part includes a third-first pattern part and a third-second pattern part spaced apart from each other in the second direction with the folding axis interposed therebetween.

13 . The display substrate of claim 12 , wherein a length in the first direction of a third pattern of the third-first pattern part is the same as a length in the first direction of a third pattern of the third-second pattern part.

14 . The display substrate of claim 1 , wherein the base material further comprises: a first hinge portion and the second hinge portion connected to the first side surface and spaced apart in the second direction, and
wherein first hinge portion and the second hinge portion are in non-contact with the first to third outer patterns.

15 . A display substrate comprising:
a base material foldable based on a folding axis and having a first direction corresponding to the folding axis and a second direction perpendicular to the first direction; and an opening pattern in which at least one of one surface and the other surface of the base material is opened, wherein the base material includes a first side surface and a second side surface positioned in the first direction, wherein the opening pattern comprises: a first pattern part including a first outer pattern spaced apart from the first side at a position closest to the first side surface; a second pattern part provided at a position closer in the second direction from the folding axis than the first pattern part and including a second outer pattern spaced apart from the first side at a position closest to the first side surface; and a third pattern part provided at a position closest in the second direction from the folding axis than the first pattern part and the second pattern part and including a third outer pattern spaced apart from the first side at a position closest to the first side surface, and wherein a distance in the second direction between a first central axis in the first direction of the first outer pattern and a second central axis in the first direction of the second outer pattern is the same as a distance in the second direction between a third central axis in the first direction of the third outer pattern and the second central axis.

16 . The display substrate of claim 15 , wherein a distance in the first direction between the first central axis and the second central axis is the same as a distance in the first direction between the second central axis and the third central axis.

17 . The display substrate of claim 16 , wherein the first pattern part further includes a plurality of first patterns spaced from the first outer pattern along the first direction,
wherein the second pattern part further includes a plurality of second patterns spaced from the second outer pattern along the first direction, wherein the third pattern part further includes a plurality of third patterns spaced from the third outer pattern alon
