Abstract

A display device includes: a first substrate overlapping a second substrate and including a display area and a non-display area; a display element disposed in the display area and between the first substrate and the second substrate; a sealing member disposed in the non-display area and between the first substrate and the second substrate; a touch unit; and a blocking member disposed in the non-display area and on the second substrate, wherein the blocking member includes blocking patterns, each of which has a first edge and a second edge, wherein the first edge extends in a first direction, and the second edge extends in a second direction different from the first direction, wherein a length of the first edge is longer than a length of the second edge, and the second edge of one blocking pattern does not overlap the second edge of another blocking pattern along the second direction.

First claim

What is claimed is:

1. A display device comprising:
a first substrate overlapping a second substrate of the display device and including a display area and a non-display area adjacent to the display area;
a display element disposed in the display area and between the first substrate and the second substrate;
a sealing member disposed in the non-display area and between the first substrate and the second substrate;
a touch unit disposed in the display area and on the second substrate; and
at least one blocking member disposed in the non-display area and on the second substrate,
wherein the at least one blocking member includes a plurality of blocking patterns,
each of the blocking patterns has a first edge and a second edge, wherein the first edge extends in a first direction parallel to an edge of the first substrate, and the second edge extends in a second direction different from the first direction, wherein a length of the first edge is longer than a length of the second edge, and
the second edge of one blocking pattern of the plurality of blocking patterns does not overlap the second edge of another blocking pattern of the plurality of blocking patterns along the second direction.

2. The display device of claim 1 , wherein
the at least one blocking member includes: a first blocking member disposed between a first portion of the edge of the first substrate and a first portion of the sealing member; and
a second blocking member disposed between the first portion of the sealing member a the touch unit.

3. The display device of claim 2 , wherein
the first and second blocking members do not overlap the sealing member.

4. The display device of claim 2 , wherein
the first blocking member includes a plurality of first blocking patterns, a plurality of second blocking patterns, and a plurality of third blocking patterns sequentially disposed from the sealing member toward the edge of the first substrate,
wherein the plurality of first blocking patterns, the plurality of second blocking patterns, and the plurality of third blocking patterns are of the plurality of blocking patterns,
wherein the first blocking patterns are disposed side by side along the first direction,
wherein the second blocking patterns are disposed side by side along the first direction, and
wherein the third blocking patterns are disposed side by side along the first direction.

5. The display device of claim 4 , wherein
the second blocking member includes a plurality of fourth blocking patterns, a plurality of fifth blocking patterns, and a plurality of sixth blocking patterns sequentially disposed from the sealing member toward the touch unit,
wherein the plurality of fourth blocking patterns, toe plurality of fifth blocking patterns, and the plurality of sixth blocking patterns are of the plurality of blocking patterns,
wherein the fourth blocking patterns are disposed side by side along the first direction,
wherein the fifth blocking patterns are disposed side by side along the first direction, and
wherein the sixth blocking patterns are disposed side by side along the first direction.

6. The display device of claim 4 , wherein
a first line extending through a central portion of one of the first blocking patterns along the second direction is disposed between the second edges of two adjacent second blocking patterns.

7. The display device of claim 6 , wherein
a second line extending through a central portion of one of the fourth blocking patterns along the second direction is disposed between the second edges of two adjacent fifth blocking patterns.

8. The display device of claim 2 , wherein
the at least one blocking member is disposed on a same layer as the touch unit.

9. The display device of claim 8 , wherein
the display element disposed between the first substrate and the second substrate is sealed by the sealing member.

10. The display device of claim 1 , wherein
the at least one blocking member is disposed on a same layer as the touch unit.

11. The display device of claim 10 , wherein
the display element disposed between the first substrate and the second substrate is at least partially surrounded by the sealing member.

12. A display device comprising:
a first substrate overlapping a second substrate of the display device and including a display area and a non-display area around the display area;
a sealing member disposed in the non-display area and between the first substrate and the second substrate; and
a blocking member disposed in the non-display area and on the second substrate to not overlap the sealing member,
wherein the blocking member includes a plurality of first blocking patterns and a plurality of second blocking patterns, wherein the plurality of first blocking patterns are disposed side by side along a first direction parallel to an edge of the first substrate, and the plurality of second blocking patterns are disposed side by side along the first direction, and
wherein a first line extends through a central portion of one of the first blocking patterns along a second direction that is substantially perpendicular to the first direction and is positioned between the second edges of two adjacent second blocking patterns.

13. The display device of claim 12 , further comprising
a touch unit disposed in the display area and on the second substrate,
wherein the blocking member is disposed on a same layer as the touch unit.

14. The display device of claim 13 , wherein
each of the first blocking patterns and the second blocking patterns have a first edge and a second edge, wherein the first edge extends parallel with the first direction, and the second edge extends parallel with the second direction, and a length of the first edge is longer than that of the second edge.

15. The display device of claim 13 , wherein
the blocking member is disposed on a same layer as the touch unit.

16. The display device of claim 15 , further comprising
a display element disposed between the first substrate and the second substrate and seated by the sealing member.

17. The display device of claim 12 , wherein
the blocking member is disposed on a same layer as a touch unit of the display device.

18. The display device of claim 17 , further comprising
a display element disposed between the first substrate and the second substrate and sealed by the sealing member.

19. A display device comprising:
a first substrate including a first area and a second area at least partially surrounding the first area;
a second substrate overlapping the first substrate;
a display element disposed in the first area;
a sealing member disposed in the second area and between the first substrate and the second substrate;
