1. A substrate for display comprising:
one surface and the other surface opposite to the one surface and foldable based on a folding axis; and
wherein the substrate is defined in a first direction corresponding to the folding axis and a second direction perpendicular to the first direction,
the substrate includes:
a first region including the folding axis; and
a second region that does not include the folding axis and is located farther from the folding axis in the second direction than the first region,
a plurality of first through-holes are formed in the first region, and a plurality of second through-holes are formed in the second region,
the second through-hole includes a 2-1 opening region in which the one surface is open and a 2-2 opening region in which the other surface is open, and
the second region includes a variable region in which a size of the 2-1 opening region and a size of the 2-2 opening region of at least one of the second through-holes are different,
the size of the 2-1 opening region is larger than the size of the 2-2 opening region, and
the size of the 2-1 opening region is not more than twice the size of the 2-2 opening region.
