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.

First claim

What is claimed is:

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:
an organic layer;
a protrusion pattern which is protruded from the organic layer; and
an opening which is disposed in the organic layer, and overlapping the sealing member, and
wherein the opening does not overlap with the protrusion pattern,
wherein the non-display area comprises a first area in which the sealing member is not disposed, and a second area which is disposed between the first area and the display area, and the opening is disposed in the second area.

2. The display device of claim 1 , wherein the opening extends in a thickness direction of the organic layer, and a depth of the opening is the same as a thickness of the organic layer.

3. The display device of claim 1 , wherein the second 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 organic layer overlapping the second area has a thickness thinner than that of the organic layer disposed in the first area.

7. The display device of claim 6 , wherein the organic layer has an inclined surface between the second area and the first 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 organic layer 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:
an organic layer;
a protrusion pattern which is protruded from the organic layer; and
an opening which is disposed in the organic layer, and overlapping the sealing member, and
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 organic layer, the protrusion pattern and the sealing member are made of a black material.

16. The display device of claim 1 , wherein the organic layer 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.
