15 Claims

1. A light-emitting device comprising:

a light-emitting panel comprising a light-emitting element;

a first support panel configured to support the light-emitting panel;

a second support panel configured to support the light-emitting panel; and

a third support panel configured to support the light-emitting panel,

wherein the light-emitting panel comprises a first region, a second region, a third region, a fourth region, and a fifth region,

wherein flexibility of each of the first region, the second region, the third region, the fourth region, and the fifth region is higher than flexibility of the first support panel,

wherein the flexibility of each of the first region, the second region, the third region, the fourth region, and the fifth region is higher than flexibility of the second support panel,

wherein the flexibility of each of the first region, the second region, the third region, the fourth region, and the fifth region is higher than flexibility of the third support panel,

wherein the first support panel and the first region overlap each other,

wherein the second support panel and the third region overlap each other,

wherein the third support panel and the fifth region overlap each other,

wherein the second region is provided between the first region and the third region,

wherein the second region does not overlap with the first support panel, the second support panel, and the third support panel,

wherein the fourth region is provided between the third region and the fifth region,

wherein the fourth region does not overlap with the first support panel, the second support panel, and the third support panel,

wherein the light-emitting device is configured to be folded in three parts when one of the second region and the fourth region is bent inward and the other of the second region and the fourth region is bent outward,

wherein a gap between the first region and the third region is made smaller as farther from the second region when the light-emitting device is folded in three parts, and

wherein a gap between the third region and the fifth region is made smaller as farther from the fourth region when the light-emitting device is folded in three parts.
