Abstract

A liquid crystal display is provided. A liquid crystal display comprising a first substrate which comprises a display area and a non-display area, a second substrate which faces the first substrate, a sealing member which is disposed in the non-display area between the first substrate and the second substrate, wherein the first substrate comprises a light-shielding pattern, a column spacer which is protruded from the light-shielding pattern toward the second substrate to maintain an interval between the first substrate and the second substrate, an opening which is disposed in the light-shielding pattern, and overlapping the sealing member.

Claims (32)

1. A liquid crystal display comprising:

a first substrate which comprises a display area and a non-display area;

a second substrate which faces the first substrate; and

a sealing member which is disposed in the non-display area between the first substrate and the second substrate

wherein the first substrate comprises:

a light-shielding pattern;

a column spacer which is protruded from the light-shielding pattern toward the second substrate to maintain an interval between the first substrate and the second substrate; and

an opening which is disposed in the light-shielding pattern, and overlapping the sealing member,

wherein the non-display area comprises a light-shielding area in which the sealing member is not disposed, and a sealing area having a shape of a closed curve which surrounds the light-shielding area, and the opening is disposed in the sealing area.

2. The liquid crystal display of claim 1 , wherein the opening extends in a thickness direction of the light-shielding pattern, and a depth of the opening is the same as a thickness of the light-shielding pattern.

3. The liquid crystal display of claim 1 , wherein the opening includes a plurality of openings which have a regularly spaced interval.

4. The liquid crystal display of claim 3 , wherein the openings have a same shape and a same size.

5. The liquid crystal display of claim 1 , wherein the light-shielding pattern overlapping the sealing area has a thickness thinner than that of the light-shielding pattern disposed in the light-shielding area.

6. The liquid crystal display of claim 5 , wherein the light-shielding pattern has an inclined surface between the sealing area and the light-shielding area.

7. The liquid crystal display of claim 1 , wherein the interior of the opening is completely filled by the sealing member.

8. The liquid crystal display of claim 1 , wherein a dummy wiring is further included at the bottom of the light-shielding pattern disposed on the sealing area.

9. The liquid crystal display of claim 8 , wherein the dummy wiring is formed by extension of wirings disposed on the display area.

10. The liquid crystal display of claim 8 , wherein, the wiring of the dummy wiring disposed on the display area has a disconnected portion at a boundary between the display area and the non-display area.

11. The liquid crystal display of claim 1 , wherein an upper portion of the opening is wider than a lower portion of the opening and the opening has an inclined surface between the upper portion and the lower portion.

12. A liquid crystal display comprising:

a first substrate which comprises a display area and a non-display area;

a second substrate which faces the first substrate; and

a sealing member which is disposed in the non-display area between the first substrate and the second substrate

wherein the first substrate comprises:

a light-shielding pattern;

a column spacer which is protruded from the light-shielding pattern toward the second substrate to maintain an interval between the first substrate and the second substrate; and

an opening which is disposed in the light-shielding pattern, and overlapping the sealing member, and

wherein the opening comprises at least one or more openings having shapes different from each other.

13. The liquid crystal display of claim 1 , wherein the height of the sealing member is higher than the height of the column spacer, and

wherein an alignment layer is disposed between the sealing member and the light-shielding pattern.

14. The liquid crystal display of claim 1 , wherein the light-shielding pattern, the column spacer and the sealing member are made of a black material.

15. The liquid crystal display of claim 1 , wherein the light-shielding pattern and the column spacer are photosensitive materials and formed of a same material through a same process, and the sealing member is made of a non-photosensitive material.
