## Abstract

According to one embodiment, a liquid crystal display comprising a first substrate, a second substrate opposed the first substrate, a liquid crystal layer between the first substrate and the second substrate, a light-shielding layer including a first light-shield formed along a first direction and a second light-shield formed along a second direction and crossing the first light-shield, and a spacer which maintains a gap between the first substrate and the second substrate, the spacer overlapping a crossing region where the first light-shield and the second light-shield cross each other and including an exposed region outside the light-shielding layer in a planar view.

## Claims

### Claim 1

A liquid crystal display comprising:
a first substrate including a control line, a signal line and a first pixel electrode;
a second substrate opposed to the first substrate and including a color filter overlapping the first substrate and a light-shielding layer including a first light-shield formed along a first direction and a second light-shield formed along a second direction, crossing the first light-shield;
a liquid crystal layer between the first substrate and the second substrate; and
a spacer which maintains a gap between the first substrate and the second substrate, wherein
the spacer overlaps a crossing region where the first light-shield and the second light-shield cross each other and includes a first exposed region and a second exposed region,
the first and second exposed regions are exposed from the light-shielding layer and overlap the color filter in a planar view,
and a center of the spacer overlaps an exposed region in the planar view.

### Claim 2 (depends on 1)

The liquid crystal display of claim 1, wherein
an area of the first exposed region is the same area of the second exposed region.

### Claim 3 (depends on 1)

The liquid crystal display of claim 1, wherein
an area of the first exposed region is greater than an area of the second exposed region.

### Claim 4 (depends on 1)

The liquid crystal display of claim 1, wherein
at least one of the first light shield and the second light shield defines an edge of each of the first and second exposed regions.

### Claim 5 (depends on 1)

The liquid crystal display of claim 1, wherein
the spacer further includes a third exposed region overlapping the color filter in a planar view.

### Claim 6 (depends on 5)

The liquid crystal display of claim 5, wherein
an area of the first exposed region is greater than an area of the second exposed region and an area of the third exposed region.

### Claim 7 (depends on 5)

The liquid crystal display of claim 5, wherein
an area of the second exposed region is greater than an area of the third exposed region.

### Claim 8 (depends on 5)

The liquid crystal display of claim 5, wherein
an area of the second exposed region and an area of the third exposed region are the same, while an area of the first exposed region is different from that of the second and third exposed regions.

### Claim 9 (depends on 8)

The liquid crystal display of claim 8, wherein
the area of the first exposed region is greater than that of the second and third exposed regions.

### Claim 10 (depends on 5)

The liquid crystal display of claim 5, wherein
at least one of the first light shield and the second light shield defines an edge of each of the first, second and third exposed regions.

### Claim 11 (depends on 1)

The liquid crystal display of claim 1, wherein
the center of the spacer overlaps the color filter in the planar view.
