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.
Claims8
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.
