Abstract
Official abstract text for this publication.
A highly portable and highly browsable light-emitting device is provided. A light-emitting device that is less likely to be broken is provided. The light-emitting device has a strip-like region having high flexibility and a strip-like region having low flexibility that are arranged alternately. In the region having high flexibility, a light-emitting panel and a plurality of spacers overlap with each other. In the region having low flexibility, the light-emitting panel and a support overlap with each other. When the region having high flexibility is bent, the angle between normals of facing planes of the two adjacent spacers changes according to the bending of the light-emitting panel; thus, a neutral plane can be formed in the light-emitting panel or in the vicinity of the light-emitting panel.
First claim
Opening claim text (preview).
1 . A light-emitting device comprising: a light-emitting panel including a light-emitting element, wherein the light-emitting device is configured to be folded in two parts such that a light-emitting surface of the light-emitting panel faces inward, wherein the light-emitting device includes a first portion, a second portion and a connection portion between the first portion and the second portion, wherein the connection portion includes a spacer controlling a folded status of the light-emitting device, and wherein the light-emitting device includes a light-blocking layer provided to overlap the connection portion or the spacer. 2 . The light-emitting device according to claim 1 , wherein the spacer includes a plurality of spacers, and wherein the folded status of the light-emitting device is controlled by contacting two adjacent spacers of the plurality of spacers. 3 . A light-emitting device comprising: a light-emitting panel including a light-emitting element, wherein the light-emitting device is configured to be folded in two parts such that a light-emitting surface of the light-emitting panel faces inward, wherein the light-emitting device includes a first portion, a second portion and a connection portion between the first portion and the second portion, wherein the connection portion includes a spacer controlling a folded status of the light-emitting device, wherein the light-emitting device includes a light-blocking layer provided to overlap the connection portion or the spacer, and wherein the connection portion and the spacer are not seen from the light-emitting surface of the light-emitting panel by the light-blocking layer and the light-emitting panel. 4 . The light-emitting device according to claim 3 , wherein the spacer includes a plurality of spacers, and wherein the folded status of the light-emitting device is controlled by contacting two adjacent spacers of the plurality of spacers.
