1. A display panel comprising:
a first region, a second region, a third region, and a first component,
wherein the first region comprises a first part of a display region,
wherein the second region comprises a second part of the display region,
wherein the third region comprises a third part of the display region,
wherein the first component is provided on and in contact with an opposite side of a display surface of the display panel,
wherein the first component is in contact with at least the second region,
wherein the second region is capable of being bent with the first component facing outward,
wherein the first component comprises a first elastic body and a second elastic body,
wherein an elastic modulus of the second elastic body is different from an elastic modulus of the first elastic body,
wherein the first elastic body is in contact with a first surface of the second elastic body,
wherein a second surface of the second elastic body is in contact with the second region, the entire second surface which is in contact with the second region being continuous both when the second region is bent and the second region is not bent, and
wherein the second surface of the second elastic body is an opposite surface of the first surface of the second elastic body.
