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 (52)

1. A semiconductor device comprising:

an exterior unit comprising glass;

a light-emitting panel over the exterior unit;

a circuit for driving the light-emitting panel over the light-emitting panel;

a metal plate over the light-emitting panel;

an adhesive bonding the metal plate to the exterior unit;

a secondary battery over the metal plate; and

an outer lid over the secondary battery,

wherein the outer lid overlaps with the metal plate without the secondary battery provided therebetween,

wherein the light-emitting panel comprises a light-emitting element over a first substrate, the first substrate being flexible;

wherein the light-emitting panel comprises a curved edge portion,

wherein a terminal portion is provided on a portion of the curved edge portion which is not bent,

wherein the terminal portion is electrically connected to the circuit,

wherein the terminal portion faces the light-emitting panel,

wherein the metal plate comprises a region not overlapping with the circuit, and

wherein the secondary battery does not overlap with the terminal portion.

2. The semiconductor device according to claim 1 , further comprising:

a flexible printed circuit.

3. The semiconductor device according to claim 2 ,

wherein the terminal portion is provided on the portion of the curved edge portion which is not bent, and

wherein the terminal portion is electrically connected to the circuit.

4. A semiconductor device comprising:

a glass plate;

a display panel over the glass plate;

a circuit for driving the display panel over the display panel;

a metal plate over the display panel;

an adhesive bonding the metal plate to the glass plate; and

a secondary battery over the metal plate and overlapping with the display panel,

wherein the display panel comprises a light-emitting element over a first substrate, the first substrate being flexible,

wherein the display panel comprises a curved edge portion,

wherein a terminal portion is provided on a portion of the curved edge portion which is not bent,

wherein the terminal portion is electrically connected to the circuit,

wherein the metal plate comprises a region not overlapping with the circuit, and

wherein the secondary battery does not overlap with the terminal portion.

5. The semiconductor device according to claim 4 , further comprising:

a flexible printed circuit.

6. The semiconductor device according to claim 5 ,

wherein the terminal portion is provided on the portion of the curved edge portion which is not bent, and

wherein the terminal portion is electrically connected to the circuit.

7. A semiconductor device comprising:

an exterior unit;

a light-emitting panel over the exterior unit;

a circuit over the light-emitting panel;

a layer comprising a metal over the circuit;

a secondary battery over the layer comprising a metal; and

a first lid over the secondary battery,

wherein each of the light-emitting panel and the circuit is provided in a first space formed between the exterior unit and the layer comprising a metal,

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

wherein a light-emitting region of the light-emitting panel comprises a curved edge portion, and

wherein the light-emitting panel comprises a curved edge portion on which a terminal portion is provided.

8. The semiconductor device according to claim 7 , further comprising:

a flexible printed circuit.
