Abstract

According to one embodiment, a liquid crystal display includes a first substrate, a second substrate including an insulating substrate, a first color filter, a second color filter, a first light-shielding layer, a second light-shielding layer, a first spacer and a second spacer, and a sealing member surrounding the second spacer and including a filler, and the first spacer having a same height as that of the second spacer, being in contact with the first substrate, the filler being interposed between the second spacer and the first substrate, and a thickness from the inner surface of the insulating substrate to a bottom of the second spacer being less than a thickness from the inner surface of the insulating substrate to a bottom of the first spacer.

Claims (28)

1. A liquid crystal display comprising:

a display area which displays images;

a non-display area surrounding the display area;

a first substrate comprising pixels in the display area;

a second substrate comprising an insulating substrate, a first color filter disposed in the display area, a second color filter disposed in the non-display area, a first light-shielding layer disposed in the display area and provided on the first substrate side of the first color filter, a second light-shielding layer disposed in the non-display area and provided on the first substrate side of the second color filter, a first spacer disposed in the display area and a second spacer disposed in the non-display area, the second substrate opposing the first substrate; and

a sealing member disposed in the non-display area to surround the second spacer and comprising a filler, which attaches the first substrate and the second substrate together, wherein

the first light-shielding layer is shaped in such a manner that the first light-shielding layer allows the light to pass through the display area,

the first color filter and the second color filter being provided on an inner surface of the insulating substrate, which opposes the first substrate, and

the first spacer having a same height as that of the second spacer along a direction from the second substrate to the first substrate, being in contact with the first substrate, the filler being interposed between the second spacer and the first substrate, and a thickness from the inner surface of the insulating substrate to a bottom of the second spacer being less than another thickness from the inner surface of the insulating substrate to another bottom of the first spacer.

2. The liquid crystal display of claim 1 , wherein

the second color filter is located in a position which overlaps the second spacer, and is connected with the first color filter.

3. The liquid crystal display of claim 1 , further comprising:

a third color filter disposed in the non-display area and spaced apart from the second color filter,

wherein the second spacer overlaps the second light-shielding layer disposed between the second color filter and the third color filter.

4. The liquid crystal display of claim 3 , wherein the second color filter and the third color filter are a same color.

5. The liquid crystal display of claim 1 , wherein the second color filter is disposed in a position which overlaps the second spacer, and has a thickness less than that of the first color filter.

6. The liquid crystal display of claim 1 , wherein

the second light-shielding layer is disposed in a position which overlaps the second spacer, and has a thickness less than that of the first light-shielding layer.

7. The liquid crystal display of claim 1 , wherein

a width of a surface of the second spacer is greater than a diameter of the filler.

8. The liquid crystal display of claim 1 , wherein

the second color filter is disposed in a position which overlaps the second spacer, and comprises a slit.

9. The liquid crystal display of claim 1 , further comprising:

a third color filter disposed in the non-display area and adjacent to and in contact with the second color filter,

wherein

the second light-shielding layer covers the second color filter and the third color filter.

10. The liquid crystal display of claim 9 , wherein

the first color filter, the second color filter and the third color filter are connected together.
