## Abstract

A display device includes a first substrate comprising an insulating film, a first organic layer on the insulating film, and a plurality of pixels arranged in a matrix in an active area. The display device further includes a second substrate comprising a black matrix and a second organic layer stacked on the black matrix. The display device also includes a seal material that attaches the first substrate and the second substrate in a circumference area outside the active area. The first organic layer includes a first opening portion which exposes the insulating film, the second organic layer includes a second opening portion which exposes the black matrix, and the first opening portion and the second opening portion overlap the seal material.

## Claims

### Claim at position 1

1: A display device comprising:
a first substrate including a first insulating substrate and a first organic insulating film on the first insulating substrate;
a second substrate including a second insulating substrate, a light shielding layer on the second insulating substrate, and a color filter layer on the light shielding layer; and
a seal material between the first substrate and the second substrate, wherein
the first organic insulating film has a first segment, a second segment and a first concave portion,
the first segment is separated from the second segment by the first concave portion,
the first insulating substrate is exposed from the first organic insulating film in the first concave portion,
the color filter layer has a third segment, a fourth segment and a second concave portion,
the third segment is separated from the fourth segment by the second concave portion, the light shielding layer is exposed from the color filter layer in the second concave portion,
the first concave portion overlaps the second concave portion, and
the seal material overlaps the first concave portion and the second concave portion.

### Claim at position 2 (depends on 1)

2: The display device of claim 1, wherein a width of the first concave portion in a first direction is smaller than a width of the second concave portion in the first direction.

### Claim at position 3 (depends on 2)

3: The display device of claim 2, further comprises a liquid crystal layer surrounded by the seal material, wherein
the liquid crystal layer overlaps a part of the first segment and a part of the third segment,
the seal material overlaps the other part of the first segment and the other part of the third segment, and
the second segment and the fourth segment overlap the seal material.

### Claim at position 4 (depends on 3)

4: The display device of claim 3, further comprise a pillar-shaped spacer between the first segment and the third segment, wherein
the pillar-shaped spacer is located inside the seal material.

### Claim at position 5 (depends on 4)

5: The display device of claim 4, further comprises a linear spacer between the second segment and the fourth segment, wherein
the seal material is located between a top surface of the linear spacer and the fourth segment.

### Claim at position 6 (depends on 5)

6: The display device of claim 5, wherein
the third segment has a linear shape, and surrounds an active area, and
the fourth segment has a linear shape, and surrounds the third segment.

### Claim at position 7 (depends on 6)

7: The display device of claim 6, wherein
the second concave portion has a linear shape, and surrounds the third segment.
