Abstract

An object of one embodiment of the present invention is to provide a more convenient highly reliable light-emitting device which can be used for a variety of applications. Another object of one embodiment of the present invention is to manufacture, without complicating the process, a highly reliable light-emitting device having a shape suitable for its intended purpose. In a manufacturing process of a light-emitting device, a light-emitting panel is manufactured which is at least partly curved by processing the shape to be molded after the manufacture of an electrode layer and/or an element layer, and a protective film covering a surface of the light-emitting panel which is at least partly curved is formed, so that a light-emitting device using the light-emitting panel has a more useful function and higher reliability.

Claims (38)

1. A light-emitting device comprising:

a first member and a second member each comprising a first planar portion, a first curved portion, a second planar portion, a second curved portion, and a third planar portion;

an active-matrix light-emitting panel between a first side of the first member and a first side of the second member, the active-matrix light-emitting panel having a flexibility; and

a protective film on a second side of the second member,

wherein the first curved portion is positioned between the first planar portion and the second planar portion,

wherein the second curved portion is positioned between the second planar portion and the third planar portion, and

wherein the active-matrix light-emitting panel is in contact with the first planar portion, the first curved portion, the second planar portion, the second curved portion, and the third planar portion.

2. The light-emitting device according to claim 1 ,

wherein the active-matrix light-emitting panel comprises a connection terminal electrode electrically connected to an FPC.

3. The light-emitting device according to claim 1 ,

wherein the active-matrix light-emitting panel is bonded to the second member with an adhesive layer so that the active-matrix light-emitting panel has a shape reflecting a shape of the second member.

4. A light-emitting device comprising:

a first member and a second member each comprising a first planar portion, a first curved portion, a second planar portion, a second curved portion, and a third planar portion;

an active-matrix light-emitting panel between a first side of the first member and a first side of the second member, the active-matrix light-emitting panel having a flexibility;

a first protective film on a second side of the second member; and

a second protective film on a second side of the first member,

wherein the first curved portion is positioned between the first planar portion and the second planar portion,

wherein the second curved portion is positioned between the second planar portion and the third planar portion, and

wherein the active-matrix light-emitting panel is in contact with the first planar portion, the first curved portion, the second planar portion, the second curved portion, and the third planar portion.

5. The light-emitting device according to claim 4 ,

wherein the active-matrix light-emitting panel comprises a connection terminal electrode electrically connected to an FPC.

6. The light-emitting device according to claim 4 ,

wherein the active-matrix light-emitting panel is bonded to the second member with an adhesive layer so that the active-matrix light-emitting panel has a shape reflecting a shape of the second member.

7. A light-emitting device comprising:

a first member and a second member each comprising a first planar portion, a first curved portion, a second planar portion, a second curved portion, and a third planar portion;

an active-matrix light-emitting panel between a first side of the first member and a first side of the second member, the active-matrix light-emitting panel having a flexibility;

a first protective film on a second side of the second member; and

a second protective film on a second side of the first member,

wherein the first curved portion is positioned between the first planar portion and the second planar portion,

wherein the second curved portion is positioned between the second planar portion and the third planar portion,

wherein the active-matrix light-emitting panel is in contact with the first planar portion, the first curved portion, the second planar portion, the second curved portion, and the third planar portion, and

wherein a first edge portion of the first protective film and the second protective film are overlapping with each other.

8. The light-emitting device according to claim 7 ,

wherein the active-matrix light-emitting panel comprises a connection terminal electrode electrically connected to an FPC.

9. The light-emitting device according to claim 7 ,

wherein the active-matrix light-emitting panel is bonded to the second member with an adhesive layer so that the active-matrix light-emitting panel has a shape reflecting a shape of the second member.

10. The light-emitting device according to claim 7 ,

wherein a second edge portion of the first protective film and the second protective film are overlapping with each other.
