the second region is smaller in thickness than a nearby region of the supporting substrate.
4. The display according to claim 3 , wherein
the supporting substrate includes a third region between the first region and the second region,
in a vicinity of a boundary between the second region and the third region, the thickness of the supporting substrate gradually increases from the second region toward the third region, and
in a vicinity of a boundary between the third region and the first region, the thickness of the supporting substrate gradually decreases from the third region toward the first region.
5. The display according to claim 1 , wherein the supporting substrate includes, in a vicinity of the edge in the first region thereof, a taper whose thickness is decreased toward the edge to form an inclination.
6. The display according to claim 3 , further comprising a hinge section in contact with the second region of the supporting substrate.
7. The display according to claim 6 , wherein
the hinge section has a curved shape curved at a constant curvature regardless of a folding angle of the supporting substrate, and
the supporting substrate is formed to have a curved shape corresponding to the curved shape of the hinge section in the second region.
8. The display according to claim 1 , wherein the supporting substrate is integrally formed.
9. The display according to claim 8 , wherein the supporting substrate is made of an elastomer.
