Abstract

According to an embodiment, a display device includes a lower electrode, a rib including a pixel aperture, a partition including a conductive lower portion on the rib and an upper portion protruding from a side surface of the lower portion, an organic layer covering the lower electrode, an upper electrode which is in contact with the side surface of the lower portion, a first sealing layer which is formed of an inorganic material and covers a display element, a first resin layer located above the first sealing layer, and a color filter located between the first sealing layer and the first resin layer.

Claims (53)

1 . A display device comprising:

a lower electrode;

a rib comprising a pixel aperture which overlaps the lower electrode;

a partition including a conductive lower portion provided on the rib and an upper portion which protrudes from a side surface of the lower portion;

an organic layer which covers the lower electrode through the pixel aperture and emits light based on application of voltage;

an upper electrode which covers the organic layer and is in contact with the side surface of the lower portion;

a first sealing layer which is formed of an inorganic material and covers a display element which includes the lower electrode, the organic layer and the upper electrode;

a first resin layer located above the first sealing layer; and

a color filter located between the first sealing layer and the first resin layer.

2 . The display device of claim 1 , further comprising a light-shielding layer which faces the partition via the first sealing layer.

3 . The display device of claim 2 , wherein

an end portion of the color filter is located between the first sealing layer and the light-shielding layer.

4 . The display device of claim 2 , wherein

an end portion of the light-shielding layer is located between the first sealing layer and the color filter.

5 . The display device of claim 1 , wherein

the color filter is thicker than the first sealing layer.

6 . The display device of claim 1 , wherein

an end portion of the color filter is located above the partition.

7 . The display device of claim 1 , further comprising a second sealing layer which is formed of an inorganic material and covers the first resin layer.

8 . The display device of claim 7 , wherein

an end portion of the first resin layer is located in a surrounding area around a display area including the display element and is covered with the first sealing layer and the second sealing layer, and

the first sealing layer is in contact with the second sealing layer in the surrounding area.

9 . The display device of claim 7 , further comprising a third sealing layer which is formed of an inorganic material and covers the first sealing layer, wherein

the color filter is located between the third sealing layer and the first resin layer.

10 . The display device of claim 9 , wherein

an end portion of the first resin layer is located in a surrounding area around a display area including the display element and is covered with the second sealing layer and the third sealing layer, and

the second sealing layer is in contact with the third sealing layer in the surrounding area.

11 . A display device comprising:

a lower electrode;

a rib comprising a pixel aperture which overlaps the lower electrode;

a partition including a conductive lower portion provided on the rib and an upper portion which protrudes from a side surface of the lower portion;

an organic layer which covers the lower electrode through the pixel aperture and emits light based on application of voltage;

an upper electrode which covers the organic layer and is in contact with the side surface of the lower portion;

a first sealing layer which is formed of an inorganic material and covers a display element including the lower electrode, the organic layer and the upper electrode;

a first resin layer located above the first sealing layer;

a color filter located between the first sealing layer and the first resin layer;

a light-shielding layer which faces the partition via the first sealing layer; and

a second sealing layer which is formed of an inorganic material and covers the first resin layer.

12 . The display device of claim 11 , wherein

an end portion of the color filter is located between the first sealing layer and the light-shielding layer.

13 . The display device of claim 11 , wherein

an end portion of the light-shielding layer is located between the first sealing layer and the color filter.

14 . The display device of claim 11 , wherein

the color filter is thicker than the first sealing layer.

15 . The display device of claim 11 , wherein an end portion of the color filter is located above the partition.

16 . The display device of claim 11 , wherein

an end portion of the first resin layer is located in a surrounding area around a display area including the display element and is covered with the first sealing layer and the second sealing layer, and

the first sealing layer is in contact with the second sealing layer in the surrounding area.

17 . The display device of claim 11 , further comprising a third sealing layer which is formed of an inorganic material and covers the first sealing layer, wherein

the color filter is located between the third sealing layer and the first resin layer.

18 . The display device of claim 17 , wherein

an end portion of the first resin layer is located in a surrounding area around a display area including the display element and is covered with the second sealing layer and the third sealing layer, and

the second sealing layer is in contact with the third sealing layer in the surrounding area.
