Abstract
To provide a method for manufacturing a lightweight light-emitting device having a light-emitting region on a curved surface. The light-emitting region is provided on a curved surface in such a manner that a light-emitting element is formed on a flexible substrate supported in a plate-like shape and the flexible substrate deforms or returns.

(canceled)
A light-emitting device comprising:
- a first region having a flat plate-like shape;
- a second region having a curved shape, the first region and the second region being continuously provided;
- a light-emitting region provided across the first region and the second region;
- a substrate;
- a first layer, comprising a plurality of light-emitting elements forming the light-emitting region, over the substrate;
- a second layer, comprising a resin, over the first layer;
- and
- a member, configured to change its shape, over the second layer,
- wherein the second layer is provided at a light-emitting surface side of the plurality of light-emitting elements,
- wherein the member selectively overlaps the second region, and
- wherein a first portion of the light-emitting region overlapping the first region does not overlap with the member.
