Abstract

Disclosed is a display device including a plurality of pixels, a first inorganic film, a light-shielding film, a resin film, and a second inorganic film. The plurality of pixels each has a light-emitting element including a pixel electrode, an electroluminescence layer over the pixel electrode, and a counter electrode over the electroluminescence layer. The first inorganic film is located over the counter electrode. The light-shielding film is located over the first inorganic film and has a plurality of openings overlapping the pixel electrodes of the plurality of pixels. The resin film is located over the light-shielding film and the first inorganic film and is in contact with the first inorganic film. The second inorganic film is located over the resin film.

Claims (48)

1 . A display device comprising:

a plurality of pixels each comprising a light-emitting element including a pixel electrode, an electroluminescence layer over the pixel electrode, and a counter electrode over the electroluminescence layer;

a first inorganic film over the counter electrode;

a light-shielding film located over the first inorganic film and having a plurality of openings overlapping the pixel electrodes of the plurality of pixels;

a resin film located over the light-shielding film and the first inorganic film and in contact with the first inorganic film; and

a second inorganic film over the resin film.

2 . The display device according to claim 1 ,

wherein the light-shielding film is in contact with the first inorganic film.

3 . The display device according to claim 1 ,

wherein the resin film is in contact with the light-shielding film and the first inorganic film.

4 . The display device according to claim 1 , further comprising a cap layer between the counter electrode and the first inorganic film.

5 . The display device according to claim 4 ,

wherein the cap layer is in contact with the counter electrode.

6 . The display device according to claim 4 ,

wherein the first inorganic film is in contact with the cap layer.

7 . The display device according to claim 1 , further comprising a bank located over the pixel electrodes, having a plurality of openings exposing the pixel electrodes of the plurality of pixels, and covered by the electroluminescence layer,

wherein, in each of the plurality of pixels, a region in which the pixel electrode and the electroluminescence layer are in contact with each other is partly covered by the light-shielding film.

8 . A display device comprising:

a plurality of pixels each comprising a light-emitting element including a pixel electrode, an electroluminescence layer over the pixel electrode, and a counter electrode over the electroluminescence layer;

a light-shielding film located over the counter electrode and having a plurality of openings overlapping the pixel electrodes of the plurality of pixels;

a first inorganic film over the light-shielding film and the counter electrode;

a resin film located over and in contact with the first inorganic film; and

a second inorganic film over and in contact with the resin film.

9 . The display device according to claim 8 ,

wherein the light-shielding film is in contact with the counter electrode.

10 . The display device according to claim 8 ,

wherein the first inorganic film is in contact with the light-shielding film and the counter electrode.

11 . The display device according to claim 8 , further comprising a cap layer between the light-shielding film and the counter electrode.

12 . The display device according to claim 8 , further comprising a cap layer between the light-shielding film and the first inorganic film.

13 . The display device according to claim 8 , further comprising a bank located over the pixel electrodes, having a plurality of openings exposing the pixel electrodes of the plurality of pixels, and covered by the electroluminescence layer,

wherein, in each of the plurality of pixels, a region in which the pixel electrode and the electroluminescence layer are in contact with each other is partly covered by the light-shielding film.

14 . A display device comprising:

a plurality of pixels each comprising a light-emitting element including a pixel electrode, an electroluminescence layer over the pixel electrode, and a counter electrode over the electroluminescence layer;

a light-shielding film located between the electroluminescence layer and the counter electrode and having a plurality of openings overlapping the pixel electrodes of the plurality of pixels;

a first inorganic film over the light-shielding film and the counter electrode;

a resin film over and in contact with the first inorganic film; and

a second inorganic film over the resin film.

15 . The display device according to claim 14 ,

wherein the light-shielding film is in contact with the electroluminescence layer.

16 . The display device according to claim 14 ,

wherein the first inorganic film is in contact with the counter electrode.

17 . The display device according to claim 14 , further comprising a cap layer between the counter electrode and the first inorganic film.

18 . The display device according to claim 17 ,

wherein the cap layer is in contact with the counter electrode.

19 . The display device according to claim 17 ,

wherein the first inorganic film is in contact with the cap layer.

20 . The display device according to claim 14 , further comprising a bank located over the pixel electrodes, having a plurality of openings exposing the pixel electrodes of the plurality of pixels, and covered by the electroluminescence layer,

wherein, in each of the plurality of pixels, a region in which the pixel electrode and the electroluminescence layer are in contact with each other is partly covered by the light-shielding film.
