Abstract

A display unit including a first substrate and a second substrate that are disposed to face each other, a first organic insulating layer on the first substrate, a plurality of light-emitting elements arrayed in a display region, the display region on the first organic insulating layer and facing the second substrate and a first moisture-proof film covering the first organic insulating layer in a peripheral region, in which the peripheral region is provided on the first substrate and surrounds the display region.

Claims (34)

1. A display unit comprising:

a substrate;

a plurality of light-emitting elements disposed in a display region on the substrate, each light-emitting element including a stack structure having a first electrode layer, a luminous layer, and a second electrode layer;

a wiring layer including a portion electrically connected to the first electrode layer;

a first inorganic layer in a level between the substrate and the luminous layer;

a second inorganic layer that covers a plurality of the luminous layers;

a third inorganic layer in a level between the wiring layer and the second electrode layer;

a first organic layer in a level between the first substrate and the first electrode layer;

a second organic layer in a level between the first electrode layer and the second inorganic layer; and

a first seal section comprised of portions of the third inorganic layer and the second inorganic layer and that seals both a first edge of the first organic layer and an outer edge of the second organic layer between the third inorganic layer and the second inorganic layer.

2. The display unit according to claim 1 , further comprising a color filter layer above the second electrode layer.

3. The display unit according to claim 1 , further comprising a light-shielding film above the second electrode layer.

4. The display unit according to claim 1 , further comprising a third organic layer, of the second inorganic layer being positioned between the first organic layer and the third organic layer, the first seal section overlapping the third organic layer.

5. The display unit according to claim 4 , further comprising a transparent layer, the third organic layer being positioned between the second inorganic layer and the transparent layer, the first seal section overlapping the transparent layer.

6. The display unit according to claim 1 , further comprising a second seal section sealing a second outer edge of the first organic layer, the first sealing section being positioned between the second sealing section and the display region.

7. The display unit according to claim 6 , wherein the second seal section is comprised of portions of the second inorganic layer and the third inorganic layer.

8. The display unit according to claim 6 , wherein the first electrode has a portion that penetrates the first organic layer at the first seal section.

9. A display unit comprising:

a substrate;

a plurality of light-emitting elements disposed in a display region on the substrate, each light-emitting element including a stack structure having a first electrode layer, a luminous layer, and a second electrode layer;

a wiring layer including a portion electrically connected to the first electrode layer;

a first inorganic layer in a level between the substrate and the luminous layer;

a second inorganic layer that covers at least some of the luminous layers;

a third inorganic layer in a level between the wiring layer and the second electrode layer;

a first organic layer in a level between the first substrate and the first electrode layer;

a second organic layer in a level between the first electrode layer and the second inorganic layer; and

a first seal section comprised of portions of the third inorganic layer and the second inorganic layer and that seals a first edge of the first organic layer and an outer edge of the second organic layer between the third inorganic layer and the second inorganic layer.

10. The display unit according to claim 9 , further comprising a color filter layer above the second electrode layer.

11. The display unit according to claim 9 , further comprising a light-shielding film above the second electrode layer.

12. The display unit according to claim 9 , further comprising a third organic layer, the second inorganic layer being positioned between the first organic layer and the third organic layer, the first seal section overlapping the third organic layer.

13. The display unit according to claim 12 , further comprising a transparent layer, the third organic layer being positioned between the second inorganic layer and the transparent layer, the first seal section overlapping the transparent layer.

14. The display unit according to claim 12 , further comprising a second seal section sealing a second outer edge of the first organic layer, the first sealing section being positioned between the second sealing section and the display region.

15. The display unit according to claim 14 , wherein the second seal section is comprised of portions of the second inorganic layer and the third inorganic layer.

16. The display unit according to claim 14 , wherein the first electrode has a portion that penetrates the first organic layer at the first seal section.
