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.

First claim

What is claimed is:

1. A light-emitting module comprising:
a housing comprising a planar portion, and a first curved portion and a second curved portion which are extended from the planar portion; and
an active-matrix light-emitting panel having a flexibility,
wherein the active-matrix light-emitting panel is bonded to the housing with an adhesive layer,
wherein a display portion of the active-matrix light-emitting panel comprises a first portion in contact with the planar portion, a second portion in contact with the first curved portion, and a third portion in contact with the second curved portion, and
wherein a periphery of the display portion overlaps with a fourth portion which is located inside to a periphery of the planar portion in a plan view.

2. The light-emitting module, according to claim 1 ,
wherein the active-matrix light-emitting panel comprises a connection terminal electrode electrically connected to an FPC, and
wherein the connection terminal electrode overlaps with the fourth portion.

3. The light-emitting module, according to claim 2 ,
wherein the active-matrix light-emitting panel comprises a connection terminal electrode electrically connected to an FPC, and
wherein the connection terminal electrode overlaps with a fifth portion between the periphery of the display portion and the periphery of the planar portion.

4. The light-emitting module, according to claim 1 ,
wherein the active-matrix light-emitting panel is bonded to the housing with the adhesive layer so that the active-matrix light-emitting panel has a shape reflecting a shape of the housing.

5. A light-emitting module comprising:
a housing comprising a planar portion, and a first curved portion and a second curved portion which are extended from the planar portion;
an active-matrix light-emitting panel including an organic EL element; and
an adhesive layer between the active-matrix light-emitting panel and the housing,
wherein a display portion of the active-matrix light-emitting panel comprises a first portion in contact with the planar portion, a second portion in contact with the first curved portion, and a third portion in contact with the second curved portion, and
wherein a periphery of the display portion overlaps with a fourth portion which is located inside to a periphery of the planar portion in a plan view.

6. The light-emitting module, according to claim 5 ,
wherein the active-matrix light-emitting panel comprises a connection terminal electrode electrically connected to an FPC, and
wherein the connection terminal electrode overlaps with the fourth portion.

7. The light-emitting module, according to claim 5 ,
wherein the active-matrix light-emitting panel comprises a connection terminal electrode electrically connected to an FPC, and
wherein the connection terminal electrode overlaps with a fifth portion between the periphery of the display portion and the periphery of the planar portion.

8. The light-emitting module, according to claim 5 ,
wherein the active-matrix light-emitting panel is bonded to the housing with the adhesive layer so that the active-matrix light-emitting panel has a shape reflecting a shape of the housing.
