Abstract

A liquid crystal display device having a uniform gap between a TFT substrate and a CF substrate even in cases where a sealant is to be applied to a slim frame formed on the outside of the effective display area is provided. A liquid crystal display device includes an effective display area, a color resist coated area, and a seal area which overlaps the color resist coated area and in which a sealant for sealing liquid crystal is provided, wherein the color resist coated area overlapping the seal area has slits formed therein.

Claims (36)

1. A liquid crystal display device comprising:

a first substrate including a resin black layer and color layers formed on the resin black layer,

a second substrate opposed to the first substrate, and

spacers disposed between the first substrate and the second substrate,

a sealant bonding the first substrate and the second substrate,

wherein the color layers are separated by slits,

wherein more than one spacer is formed on each of the color layers, and the spacers specify a distance between the first substrate and the second substrate, and

wherein the spacers are surrounded by the sealant in a plan view,

wherein the spacers are not formed on the slits, and

wherein the slits overlap with the sealant in a plan view.

2. The liquid crystal display device according to claim 1 ,

wherein the slits are not formed in the resin black layer.

3. The liquid crystal display device according to claim 1 ,

wherein second spacers are formed in the display area, the second spacers and the spacers are made of the same material.

4. The liquid crystal display device according to claim 1 ,

wherein a width of each of the slits is in a range of 20 μm to 100 μm and a length of each of the slits is in a range of 0.2 mm to 0.8 mm.

5. The liquid crystal display device according to claim 1 ,

wherein the slits are formed in a grid-like pattern.

6. The liquid crystal display device according to claim 1 ,

wherein the color layers are distributed around the display area.

7. A liquid crystal display device comprising:

a display area,

a resin black layer formed in a planar shape around the display area,

color layers formed on the resin black layer,

a seal area that has a sealant for sealing liquid crystal and disposed around the display area, and spacers between a first substrate and a second substrate,

wherein the seal area has a width in a first direction and extends in a second direction that intersects the first direction,

wherein the color layers are separated by slits,

wherein widths in the first direction of the slits are larger than widths in the first direction of the color layers which are separated by the slits,

wherein the spacers do not overlap the slits, and

wherein the slits overlap with the sealant in a plan view.

8. The liquid crystal display device according to claim 7

wherein the slits are not formed in the black resin layer.

9. The liquid crystal display device according to claim 7 ,

wherein more than one spacer is formed on each of the color layers, the spacers specify a distance between the first substrate and the second substrate.

10. The liquid crystal display device according to claim 7 ,

wherein the slits are closed at the display area side in a plan view.
