the subpixels include first to third subpixels,

the display elements include first to third display elements which are provided in the first to third subpixels, respectively, and which emit light exhibiting different colors,

the sealing layers include first to third sealing layers which cover the first to third display elements, respectively,

the first sealing layer overlaps at least part of the slit as seen in plan view, and

at least one of the second sealing layer and the third sealing layer is spaced apart from the slit as seen in plan view.

3 . The display device of claim 2 , wherein

the first sealing layer intersects with the slit as seen in plan view.

4 . The display device of claim 2 , wherein

the first sealing layer includes:

a first portion which covers the first display element; and

a second portion which extends in an extension direction of the slit and covers the slit.

5 . The display device of claim 2 , wherein

the first subpixels extend in an extension direction of the slit along the slit, and

the first sealing layer extends in the extension direction and continuously covers the first display element provided in each of the first subpixels, and the slit.

6 . The display device of claim 1 , further comprising a dummy pixel area which includes a plurality of dummy subpixels and is located outside the display area, wherein

part of the partition is located in the dummy pixel area and surrounds each of the dummy subpixels.

7 . The display device of claim 6 , wherein

the slit is partly located in the dummy pixel area.

8 . The display device of claim 7 , wherein

the sealing layers include a dummy sealing layer which overlaps at least one of the dummy subpixels and at least part of the slit as seen in plan view.

9 . The display device of claim 8 , wherein

the partition further includes an outer circumferential portion located outside the dummy pixel area, and

the slit reaches the outer circumferential portion.

10 . The display device of claim 9 , wherein

in, of the dummy subpixels, at least one dummy subpixel provided in an outermost circumference of the dummy pixel area, the dummy sealing layer is not provided.

11 . The display device of claim 9 , wherein

the slit reaches an outer edge of the outer circumferential portion.

12 . The display device of claim 1 , wherein

the partition further includes a connection portion which connects the segments across the slit.

13 . The display device of claim 12 , wherein

the connection portion is provided between the two sealing layers in an extension direction of the slit.

14 . A display device comprising:

a first subpixel and a second subpixel;

a partition which includes a conductive lower portion and an upper portion having an end portion protruding from a side surface of the lower portion, and surrounds the first subpixel and the second subpixel;

first and second display elements which are provided in the first and second subpixels, respectively, and emit light exhibiting different colors; and

first and second sealing layers which are formed of an inorganic insulating material and cover the first and second display elements, respectively, wherein

the partition includes a first segment located on the first subpixel side and a second segment located on the second subpixel side, and the first and second segments are separated by a slit, and

part of the first sealing layer is located inside the slit.

15 . The display device of claim 14 , wherein

a gap is formed under the first sealing layer in the slit.

16 . The display device of claim 14 , wherein

the first segment includes a first partition which is adjacent to the slit,

the second segment includes a second partition which is adjacent to the slit, and

both an end portion of the first sealing layer and an end portion of the second sealing layer are located above the second partition.

17 . The display device of claim 16 , further comprising:

a third subpixel which is adjacent to the first subpixel in an extension direction of the slit, and is adjacent to the second subpixel via the slit in a width direction intersecting with the extension direction;

a third display element provided in the third subpixel; and

a third sealing layer which is formed of an inorganic insulating material and covers the third display element.

18 . The display device of claim 17 , wherein

an end portion of the third sealing layer is located above the first partition.

19 . The display device of claim 17 , wherein

the first sealing layer includes:

a first portion which covers the first display element; and

a second portion which extends in the extension direction and is located inside the slit.

20 . The display device of claim 19 , wherein

part of the second portion is located between the second subpixel and the third subpixel in the width direction.
