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 (48)

1. A light-emitting device comprising:

an active-matrix light-emitting panel having a flexibility; and

a member comprising a light transmitting material,

wherein the member comprises a planar portion, and a first curved portion and a second curved portion which each extends from both ends of the planar portion,

wherein, in a view taken from a direction parallel to the both ends, the member has a concave shape,

wherein the active-matrix light-emitting panel and the member are fixed to each other along the first curved portion, the planar portion, and the second curved portion using an adhesive layer,

wherein the active-matrix light-emitting panel comprises a region between the first curved portion and a film comprising metal, a region between the planar portion and the film comprising metal, and a region between the second curved portion and the film comprising metal, and

wherein periphery of a display region of the active-matrix light-emitting panel overlaps with a region inside to a periphery of the 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 comprises a light-emitting element, and

wherein a cathode of the light-emitting element comprises at least one of an alkali metal, an alkaline earth metal, and a rare earth metal.

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

wherein the active-matrix light-emitting panel comprises a light-emitting element, and

wherein a cathode of the light-emitting element comprises at least one of europium and ytterbium.

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

wherein the active-matrix light-emitting panel comprises a light-emitting element,

wherein the light-emitting element comprises a layer between a cathode and a light-emitting layer, and

wherein the layer comprises an aromatic amine compound.

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

wherein the active-matrix light-emitting panel comprises a light-emitting element, and

wherein the light-emitting element comprises a light-emitting layer comprising a guest material and a host material.

7. A light-emitting device comprising:

an active-matrix light-emitting panel having a flexibility; and

a member comprising a light transmitting material,

wherein the member comprises a planar portion, a first curved portion, and a second curved portion,

wherein the first curved portion is positioned between a first side of the member extending to a first direction and the planar portion,

wherein the second curved portion is positioned between a second side of the member extending to the first direction and the planar portion,

wherein, in a view taken from the first direction, the member has a concave shape,

wherein the active-matrix light-emitting panel and the member are fixed to each other along the first curved portion, the planar portion, and the second curved portion using an adhesive layer,

wherein the active-matrix light-emitting panel comprises a region between the first curved portion and a film comprising metal, a region between the planar portion and the film comprising metal, and a region between the second curved portion and the film comprising metal, and

wherein periphery of a display region of the active-matrix light-emitting panel overlaps with a region inside to a periphery of the planar portion.

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 comprises a light-emitting element, and

wherein a cathode of the light-emitting element comprises at least one of an alkali metal, an alkaline earth metal, and a rare earth metal.

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

wherein the active-matrix light-emitting panel comprises a light-emitting element, and

wherein a cathode of the light-emitting element comprises at least one of europium and ytterbium.

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

wherein the active-matrix light-emitting panel comprises a light-emitting element,

wherein the light-emitting element comprises a layer between a cathode and a light-emitting layer, and

wherein the layer comprises an aromatic amine compound.

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

wherein the active-matrix light-emitting panel comprises a light-emitting element, and

wherein the light-emitting element comprises a light-emitting layer comprising a guest material and a host material.
