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 (30)

1. A display device comprising:

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

a sealing member which is disposed on the substrate and overlaps the non-display area

wherein the substrate comprises:

a light-shielding pattern;

a protrusion pattern which is protruded from the light-shielding pattern; and

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

wherein the opening does not overlap with the protrusion pattern, and

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

2. The display device 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 display device of claim 1 , wherein the sealing area has a shape of a closed curve.

4. The display device of claim 3 , wherein the opening includes a plurality of openings which have a regularly spaced interval.

5. The display device of claim 4 , wherein the openings have a same shape and a same size.

6. The display device of claim 3 , 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.

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

8. The display device of claim 1 , wherein the interior of the opening is completely filled by the sealing member.

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

10. The display device of claim 9 , wherein the dummy wiring is formed by extension of wirings disposed on the display area.

11. The display device of claim 9 , 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.

12. The display device 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.

13. A display device comprising:

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

a sealing member which is disposed on the substrate and overlaps the non-display area; wherein the first substrate comprises:

a light-shielding pattern;

a protrusion pattern which is protruded from the light-shielding pattern; and

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

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

14. The display device of claim 1 , wherein the height of the sealing member is higher than the height of the protrusion pattern.

15. The display device of claim 1 , wherein the light-shielding pattern, the protrusion pattern and the sealing member are made of a black material.

16. The display device of claim 1 , wherein the light-shielding pattern and the protrusion pattern are photosensitive materials and formed of a same material through a same process, and the sealing member is made of a non-photosensitive material.
