Abstract

A display device is disclosed including a plurality of pixels arranged above a substrate, and a sealing film arranged above the substrate so as to cover the plurality of pixels, wherein the sealing film includes a stacked first inorganic film, second inorganic film and third inorganic film, a first organic film arranged between the first inorganic film and the second organic film, and a second organic film arranged between the second inorganic film and the third inorganic film, and wherein the first organic film is divided into a plurality of regions by a first partition wall, and the second organic film is divided into a plurality of regions by a second partition wall.

Claims (16)

1. A display device comprising:

a plurality of pixels arranged above a substrate; and

a sealing film arranged above the substrate so as to cover the plurality of pixels;

wherein

the sealing film includes a stacked first inorganic film, second inorganic film and third inorganic film, a first organic film arranged between the first inorganic film and the second inorganic film, and a second organic film arranged between the second inorganic film and the third inorganic film, wherein the first organic film is divided into a plurality of regions by a first partition wall, and the second organic film is divided into a plurality of regions by a second partition wall, and wherein each of the regions divided by the first partition wall includes at least one pixel not included in each one of the regions divided by the second partition wall in a plan view, and each of the regions divided by the second partition wall includes at least one pixel not included in each one of the regions divided by the first partition wall in a plan view.

2. The display device according to claim 1 , wherein the first partition wall comprises a part of the second inorganic film, and the second partition wall comprises a part of the third inorganic film.

3. The display device according to claim 1 , wherein at least of the first partition wall and the second partition wall is arranged along a boundary of the plurality of pixels.

4. The display device according to claim 3 , further comprising:

a rib defining the plurality of pixels;

wherein the first partition wall is arranged along the rib.

5. The display device according to claim 4 , wherein the sealing film further includes a fourth inorganic film covering a concave/convex surface formed by the rib, and a third organic film arranged between the fourth inorganic film and the first inorganic film, the third organic film being divided into a plurality of regions by the rib.

6. The display device according to claim 5 , wherein the third organic film is comprised from a different resin material to the first organic film and the second organic film.

7. The display device according to claim 1 , wherein the plurality of pixels is regularly arranged, and at least one of the first partition wall and the second partition wall extends inclined by a certain angle with respect to a direction in which a boundary of the plurality of pixels extends in a plan view.

8. The display device according to claim 1 , wherein at least of a plurality of regions of the first organic film divided by the first partition wall and a plurality of regions of the second organic film divided by the second partition wall includes two or more regions having mutually different shapes.

9. The display device according to claim 1 , wherein at least of a plurality of regions of the first organic film divided by the first partition wall and a plurality of regions of the second organic film divided by the second partition wall has a larger plane size than each of the plurality of pixels respectively.

10. The display device according to claim 1 , wherein the first inorganic film, the second inorganic film and the third inorganic film includes at least one of silicon oxide, silicon nitride and aluminum oxide.
