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.
