Abstract
A light-emitting device includes a strip-like high flexibility region and a strip-like low flexibility region arranged alternately in a direction. The high flexibility region includes a flexible light-emitting panel. The low flexibility region includes the light-emitting panel and a support panel having a lower flexibility than that of the light-emitting panel and overlapping with the light-emitting panel. It is preferable that the light-emitting panel include an external connection electrode and that a length in the direction of a low flexibility region A that overlaps with the external connection electrode be longer than a length in the direction of a low flexibility region B that is closest to the region A.

- a second support panel;
- and
- a protective layer,
- wherein, in a state where the flexible light-emitting panel is folded, the flexible light-emitting panel comprises a first region with a first flat surface, a second region with a second flat surface, and a region bent inward between the first region and the second region so that a gap between the first flat surface and the second flat surface decreases as a distance from the region increases,
- wherein the first region of the flexible light-emitting panel and the first support panel overlap with each other,
- wherein the second region of the flexible light-emitting panel and the second support panel overlap with each other,
- wherein the region is capable of displaying an image in a state where the flexible light-emitting panel is not folded,
