Abstract

This invention provides a portable light-emitting device. It also provides a light-emitting device with a high degree of visibility. One aspect of this invention is a light-emitting device in which a strip-shaped highly flexible region and a strip-shaped low-flexibility region are alternately arranged in a first direction. The highly flexible region includes a flexible light-emitting panel, and the low-flexibility region includes a support panel and a light-emitting panel whose flexibility is lower than that of the light-emitting panel, in an overlapping manner. The light-emitting panel includes an external connection electrode, and the first-direction length of the low-flexibility region A overlapping with the external connection electrode is longer than the first-direction length of the low-flexibility region B closest to region A.
