1. A window, comprising:
a window layer that includes:
a first section;
a second section; and
a folding section that is disposed between the first section and the second section and is foldable with respect to a folding axis extending in a direction, wherein
the folding section comprises at least one opening pattern, the at least one opening pattern each including an opening penetrating from a top surface to a bottom surface of the folding section,
in a plan view, a maximum distance between two points on an inner line of the folding section that defines a single shape of the at least one opening pattern is about 10 micrometers to about 200 micrometers, the maximum distance being different from both a length and a width of the single shape,
the width of the single shape is constant in one direction perpendicular to a thickness direction of the window,
each of the first section and the second section comprises a first material, and the folding section comprises a second material having an elastic modulus lower than an elastic modulus of the first material, and
the folding section does not comprise the first material.
