## Abstract

According to one embodiment, a display device including a first substrate, a second substrate, a sealant, and a spacer, wherein the first substrate and the second substrate in an area surrounded by the sealant includes a first area and a second area located between the sealant and the first area, the spacer includes a plurality of first spacers located in the first area and a plurality of second spacers located in the second area, the first spacers are located at a first distance from each other in a first direction, the second spacers are located at a second distance from each other in the first direction, and the second distance is less than the first distance.

## Claims

### Claim 1

A display device comprising:
a first substrate;
a second substrate opposed to the first substrate;
a sealant which attaches the first substrate and the second substrate together; and
a spacer located between the first substrate and the second substrate, wherein
the first substrate and the second substrate in an area surrounded by the sealant comprises a first area, a second area located between the sealant and the first area, and a third area between the first area and the second area,
the spacer is formed of a recess and a projection opposed to the recess, and includes a plurality of first spacers located in the first area, a plurality of second spacers located in the second area, and a plurality of third spacers located in the third area,
the first spacers are located at a first distance from each other in a first direction, and are located at a fourth distance from each other in a second direction intersecting the first direction,
the second spacers are located at a second distance from each other in the first direction, and are located at a fifth distance from each other in the second direction,
the third spacers are located at a third distance from each other in the first direction, and are located at a sixth distance from each other in the second direction,
the second distance is less than the first distance,
the third distance is less than the first distance and is greater than the second distance,
the fifth distance is less than the fourth distance, and
the sixth distance is less than the fourth distance and is greater than the fifth distance.

### Claim 2 (depends on 1)

The display device of claim 1, wherein
a width of the first spacers in the first direction is a first width,
a width of the second spacers in the first direction is a second width, and
the second width is greater than or equal to the first width.

### Claim 3 (depends on 1)

The display device of claim 1, further comprising signal lines extending in a second direction intersecting the first direction, and
the first spacers and the second spacers extend along the signal lines, respectively.

### Claim 4 (depends on 1)

The display device of claim 1, wherein
the first spacers are located at a third distance from each other in a second direction intersecting the first direction,
the second spacers are located at a fourth distance from each other in the second direction, and
the fourth distance is less than the third distance.

### Claim 5 (depends on 1)

The display device of claim 1, further comprising a cover member having a curved portion and a flat portion, wherein
the first area is located in the flat portion, and
the second area is located in the curved portion.

### Claim 6 (depends on 1)

The display device of claim 1, wherein a tip portion of the projection contacts a bottom portion of the recess.

### Claim 7 (depends on 6)

The display device of claim 6, wherein
the first substrate comprises an insulating substrate, an organic insulating film located above the insulating substrate, an insulating film located above the organic insulating film, an alignment film located above the insulating film, a signal line located between the insulating substrate and the organic insulating film, and the recess,
the second substrate comprises the projection, and
the recess is formed across the alignment film, the insulating film and the organic insulating film above the signal line.
