Abstract

A display device includes a first substrate including an organic layer forming region, and an organic layer non-forming region which is provided on an outer side of the organic layer forming region; and a first partitioning wall which is provided between the organic layer forming region and the organic layer non-forming region on the first substrate.

Claims (34)

1. A display device comprising:

a first substrate including an organic layer forming region, and an organic layer non-forming region which is provided on an outer side of the organic layer forming region;

a first partitioning wall which is provided between the organic layer forming region and the organic layer non-forming region the first substrate;

a second substrate which faces the first substrate; and

a sealing agent is provided between the second substrate and the first substrate in the organic layer non-forming region,

wherein the first partitioning wall does not directly contact the first substrate and the second substrate.

2. The display device according to claim 1 , wherein a terminal for an external connection is provided in the organic layer non-forming region.

3. The display device according to claim 1 , wherein a first electrode and a second electrode are provided in the organic layer forming region on the first substrate, and wherein the second electrode is electrically connected to wiring which is provided in the organic layer non-forming region on the first substrate.

4. The display device according to claim 3 , wherein an organic layer including a light emitting layer is provided between the first electrode and the second electrode.

5. The display device according to claim 1 , further comprising: a second partitioning wall on an outer side of the organic layer forming region on the first substrate, wherein the organic layer non-forming region is provided between the first partitioning wall and the second partitioning wall.

6. The display device according to claim 1 , wherein a plurality of the organic layer non-forming regions and a plurality of the first partitioning walls are provided on the first substrate, and wherein at least a part of the plurality of first partitioning walls is provided between the neighboring organic layer non-forming regions.

7. The display device according to claim 1 , wherein the first partitioning wall is configured of an organic material.

8. The display device according to claim 1 , wherein the organic layer forming region is a pixel region which includes a plurality of pixels which are arranged in a matrix.

9. The display device according to claim 8 , further comprising: an insulation film between pixels in the organic layer forming region on the substrate, wherein the insulation film between pixels contains the same constituent material as that of the first partitioning wall.

10. The display device according to claim 8 , further comprising: a liquid repellent region in a region between columns of the plurality of pixels.

11. The display device according to claim 1 , wherein the first partitioning wall has a height in a Z-direction between five hundred nanometers and four thousand nanometers and a width in an X-direction between five micrometers and one hundred micrometers.

12. An electronic apparatus comprising:

a display device,

wherein the display device includes

a first substrate including an organic layer forming region, and an organic layer non-forming region which is provided on an outer side of the organic layer forming region;

a first partitioning wall which is provided between the organic layer forming region and the organic layer non-forming region on the first substrate;

a second substrate which faces the first substrate; and

a sealing agent is provided between the second substrate and the first substrate in the organic layer non-forming region,

wherein the first partitioning wall does not directly contact the first substrate and the second substrate.

13. The electronic apparatus according to claim 12 , wherein a terminal for an external connection is provided in the organic layer non-forming region.

14. The electronic apparatus according to claim 12 , wherein a first electrode and a second electrode are provided in the organic layer forming region on the first substrate, and wherein the second electrode is electrically connected to wiring which is provided in the organic layer non-forming region on the first substrate.

15. The electronic apparatus according to claim 14 , wherein an organic layer including a light emitting layer is provided between the first electrode and the second electrode.

16. The electronic apparatus according to claim 12 , wherein the display device further includes a second partitioning wall on an outer side of the organic layer forming region on the first substrate, wherein the organic layer non-forming region is provided between the first partitioning wall and the second partitioning wall.

17. The electronic apparatus according to claim 12 , wherein a plurality of the organic layer non-forming regions and a plurality of the first partitioning walls are provided on the first substrate, and wherein at least a part of the plurality of first partitioning walls is provided between the neighboring organic layer non-forming regions.

18. The electronic apparatus according to claim 12 , wherein the first partitioning wall is configured of an organic material.

19. The electronic apparatus according to claim 12 , wherein the organic layer forming region is a pixel region which includes a plurality of pixels which are arranged in a matrix.

20. The electronic apparatus according to claim 12 , wherein the display device further includes an insulation film between pixels in the organic layer forming region on the substrate, wherein the insulation film between pixels contains the same constituent material as that of the first partitioning wall.

21. The electronic apparatus according to claim 12 , wherein the display device further includes a liquid repellent region in a region between columns of the plurality of pixels.

22. The electronic apparatus according to claim 12 , wherein the first partitioning wall has a height in a Z-direction between five hundred nanometers and four thousand nanometers and a width in an X-direction between five micrometers and one hundred micrometers.
