Abstract

Provided are a method of manufacturing a display apparatus and the display apparatus. A method of manufacturing a display apparatus includes preparing a first substrate including a display; adhering a second substrate to the first substrate by using a sealing element; exposing the sealing element by using a blocking member including a plurality of blocking patterns arranged apart from one another; and cutting the first substrate and the second substrate along portions thereof inside the blocking member.

First claim

What is claimed is:

1. A method of manufacturing a display apparatus, the method comprising:
preparing a first substrate comprising a display thereon;
adhering a second substrate to the first substrate by using a sealing element;
exposing the sealing element by using a blocking member comprising a plurality of blocking patterns arranged apart from one another; and
cutting the first substrate and the second substrate along portions thereof underneath the blocking member.

2. The method of claim 1 , wherein the blocking member overlaps portions of the sealing element.

3. The method of claim 1 , wherein the blocking member overlaps outer end portions of the sealing element.

4. The method of claim 1 , wherein the adhering of the second substrate to the first substrate comprises:
arranging the second substrate on the first substrate; and
arranging the blocking member on the second substrate such that the blocking member overlaps a portion of the sealing element.

5. The method of claim 1 , wherein the plurality of blocking patterns are sequentially arranged apart from one another in a widthwise direction of the sealing element.

6. The method of claim 1 , wherein at least a portion of the blocking member comprises:
a first blocking pattern at least partially overlapping the sealing element; and
a second blocking pattern arranged apart from the first blocking pattern in a widthwise direction of the sealing element.

7. The method of claim 6 , wherein a width of the first blocking pattern in the widthwise direction is equal to or greater than a width of the second blocking pattern in the widthwise direction.

8. The method of claim 1 , wherein at least one of the plurality of blocking patterns has a linear shape or a dot-like shape.

9. The method of claim 1 , wherein the plurality of blocking patterns comprises a metal.

10. The method of claim 1 , further comprising forming a touch screen conductive pattern on the second substrate,
wherein the plurality of blocking patterns is formed during the forming of the touch screen conductive pattern.

11. The method of claim 1 , wherein a distance between blocking patterns adjacent to each other among the plurality of blocking patterns is within about 7 μm.

12. The method of claim 1 , wherein the blocking member overlaps three surface portions of the sealing element.

13. The method of claim 1 ,
wherein, in the exposing of the sealing element, a portion of the sealing element that does not overlap the blocking member is exposed, and
wherein a portion of the sealing element overlapping the blocking member is not exposed.

14. The method of claim 13 , wherein the width of the exposed portion of the sealing element is less than or equal to 800 μm.

15. The method of claim 1 , wherein, in the cutting of the first substrate and the second substrate, the first substrate and the second substrate are cut such that a width of the display apparatus measured with respect to the sealing element is greater than a width of the first substrate or the second substrate.

16. The method of claim 1 , wherein, in the cutting of the first substrate and the second substrate, the first substrate is cut such that the width of the first substrate increases in a direction from an outer surface of the first substrate toward an inner surface of the first substrate.

17. The method of claim 1 , wherein, in the cutting of the first substrate and the second substrate, the first substrate is cut such that a first constant portion having a constant width and a first increasing portion having an increasing width are defined.

18. The method of claim 17 , wherein, in the cutting of the first substrate and the second substrate, the first constant portion is cut by using a cutting wheel.

19. The method of claim 17 , wherein the first increasing portion is naturally cut due to internal stress of the first substrate.

20. A display apparatus manufactured according to the method of claim 1 .
