1. A display substrate comprising:
a base material that is foldable based on a folding axis,
wherein the base material is defined in a first direction corresponding to the folding axis and a second direction perpendicular to the first direction,
wherein the base material includes an opening pattern in which at least one of one surface or another surface of the base material is open,
wherein the base material includes a first side surface and a second side surface positioned in the first direction,
wherein the opening pattern includes a first pattern part, a second pattern part, and a third pattern part that are spaced apart from each other along the second direction,
wherein the first pattern part includes a plurality of first patterns spaced from each other along the first direction and provided at a position farther in the second direction from the folding axis than the second and third pattern parts,
wherein the second pattern part includes a plurality of second patterns spaced from each other along the first direction and provided at a position closer in the second direction from the folding axis than the first pattern part,
wherein the third pattern part includes a plurality of third patterns spaced from each other along the first direction and provided at a position closer in the second direction from the folding axis than the first pattern part and the second pattern part,
wherein the plurality of third patterns are in non-contact with the first side surface and the second side surface,
wherein the plurality of first patterns includes a first outer pattern positioned closest to the first side surface,
wherein the plurality of second patterns includes a second outer pattern positioned closest to the first side surface,
wherein the plurality of third patterns includes a third outer pattern positioned closest to the first side surface,
wherein the first to third outer patterns are spaced apart from the first side surface in the first direction,
wherein the first outer pattern has a first distance in the first direction from a first central axis in the first direction of the first outer pattern the first side surface,
wherein the second outer pattern has a second distance in the first direction from a second central axis in the first direction of the second outer pattern to the first side surface,
wherein the third outer pattern has a third distance in the first direction from a third central axis the first direction of the third outer pattern to the first side surface, and
wherein the first to third distances are different from each other.
