Abstract

A highly reliable light-emitting module including an organic EL element or a light-emitting device using a highly reliable light-emitting module including an organic EL element is provided. Alternatively, a method of manufacturing a highly reliable light-emitting module including an organic EL element, or a method of manufacturing a light-emitting device using a highly reliable light-emitting module including an organic EL element is provided. The light-emitting module has a structure in which a light-emitting element formed over a first substrate and a viscous material layer are sealed in a space between the first substrate and a second substrate which face each other, with a sealing material surrounding the light-emitting element. The viscous material layer is provided between the light-emitting element and the second substrate and includes a non-solid material and a drying agent which reacts with or adsorbs an impurity.

First claim

a first frame and a second frame over the substrate,
wherein the source driver circuit and the gate driver circuit are surrounded by the first frame and the second frame, and the pixel portion is surrounded by the second frame,
wherein the second frame includes an opening at a position over and between the pixel portion and the driver circuit portion, and
wherein the first frame is continuous in plan view.

2. The light-emitting module according to claim 1 , further comprising sealing material in contact with an entire outer surface of the first frame.

3. The light-emitting module according to claim 2 , wherein a width of the sealing material is larger than a width of the first frame.

4. The light-emitting module according to claim 1 , wherein the second frame shares one side of the first frame.

5. The light-emitting module according to claim 1 , further comprising a viscous material layer including a drying agent over the partition and the light-emitting element.

6. The light-emitting module according to claim 1 , wherein the light-emitting module is incorporated into a display device of a television set, a computer, a portable game machine, or a mobile phone set.

7. A light-emitting module comprising:
a pixel portion, a driver circuit portion including a source driver circuit and a gate driver circuitover a substrate, the pixel portion including a transistor, a light-emitting element and a partition over the transistor; and
a first frame over the substrate and a second frame over the partition,
wherein the source driver circuit and the gate driver circuit are surrounded by the first frame and the second frame, and the pixel portion is surrounded by the second frame,
wherein the second frame includes an opening at a position over and between the pixel portion and the driver circuit portion, and
wherein the first frame is continuous in plan view.

8. The light-emitting module according to claim 7 , further comprising a sealing material in contact with an entire outer surface of the first frame.

9. The light-emitting module according to claim 8 , wherein a width of the sealing material is larger than a width of the first frame.

10. The light-emitting module according to claim 7 , wherein the second frame shares one side of the first frame.

11. The light-emitting module according to claim 7 , further comprising a viscous material layer including a drying agent over the partition and the light-emitting element.

12. The light-emitting module according to claim 7 , wherein the light-emitting module is incorporated into a display device of a television set, a computer, a portable game machine, or a mobile phone set.

13. A light-emitting module comprising:

a first frame over the substrate and a second frame over the partition,
wherein the source driver circuit and the gate driver circuit are surrounded by the first frame and the second frame, and the pixel portion is surrounded by the second frame,
wherein the second frame includes an opening at a position over and between the pixel portion and the source driver circuit, and
wherein the first frame is continuous in plan view.

14. The light-emitting module according to claim 13 , further comprising a sealing material in contact with an entire outer surface of the first frame.

15. The light-emitting module according to claim 14 , wherein a width of the sealing material is larger than a width of the first frame.

16. The light-emitting module according to claim 13 , wherein the second frame shares one side of the first frame.

17. The light-emitting module according to claim 13 , further comprising a viscous material layer including a drying agent over the partition and the light-emitting element.

18. The light-emitting module according to claim 13 , wherein the light-emitting module is incorporated into a display device of a television set, a computer, a portable game machine, or a mobile phone set.
