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.

Claims

1. A semiconductor device comprising:

an exterior unit;

a display panel over the exterior unit;

a circuit over the display panel;

a layer comprising metal over the circuit;

a secondary battery over the layer comprising metal; and

a first lid over the secondary battery,

wherein each of the display panel and the circuit is provided in a first space formed between the exterior unit and the layer,

wherein the secondary battery is provided in a second space formed between the layer and the first lid,

wherein the display panel comprises a light-emitting element, and

wherein a light-emitting region of the display panel comprises curved edge portions.

2. The semiconductor device according to claim 1, wherein the exterior unit comprises any one of metal, glass, and plastic.
