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 (25)

1. A liquid crystal display device comprising:

a display area,

a sealant that surrounds the display area,

a first substrate and a second substrate bonded by the sealant, and

spacers disposed between the first substrate and the second substrate,

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

the color layer has a first portion and a second portion which are separated from each other in a region between the display area and the sealant,

the sealant extends along a side of the first substrate, and has a width in a width direction that is perpendicular to the extending direction of the sealant,

the spacers are not formed in an area between the first portion and the second portion,

one of the spacers is formed on the first portion, and

a plurality of the spacers are formed in the width direction on the second portion.

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

wherein a part of the first portion and a part of the second portion are overlapped with the sealant.

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

wherein a distance between the first portion and the second portion is in a range of 20 μm to 100 μm.

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

wherein the resin black layer is formed continuously in the region between the display area and the sealant.

5. The liquid crystal display device according to claim 1 , further comprising a liquid crystal layer held between the first substrate and the second substrate,

wherein the liquid crystal layer is provided in the region between the display area and the sealant.

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

wherein the spacers specify a distance between the first substrate and the second substrate.

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

wherein a size in the width direction of the first portion is different from a size in the width direction of the second portion.

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

wherein the second portion is closer to the display area than the first portion is.
