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 display apparatus comprising:
a first substrate comprising a first inner surface and a first outer surface opposite to the first inner surface;
a display element on the first inner surface of the first substrate;
a second substrate comprising a second inner surface facing the first inner surface and a second outer surface opposite to the second inner surface; and
a sealing element located between the first and second substrates, and surrounding the display element; and
wherein the first substrate further comprises a first side surface connecting the first inner surface and the first outer surface, the first side surface comprising a first curved surface and a first flat surface extending from the first curved surface toward the first outer surface in a direction from the first inner surface to the first outer surface, and
wherein the second substrate further comprises a second side surface connecting the second inner surface and the second outer surface, the second side surface comprising a second curved surface.

2. The display apparatus of claim 1 , further comprising a touch screen conductive pattern on the second substrate.

3. The display apparatus of claim 2 , further comprising a plurality of line patterns that are disposed on the second outer surface and comprise a same material as the touch screen conductive pattern.

4. The display apparatus of claim 1 , wherein the second curved surface is curved in a second direction from the second outer surface to the second inner surface such that a vertex of the second curved surface is adjacent to the sealing element.

5. The display apparatus of claim 4 , wherein the second side surface further comprises a second flat surface between the second outer surface and the second curved surface.

6. The display apparatus of claim 1 , wherein the sealing element comprises an inner side surface toward the display element and an outer side surface opposite to the inner side surface.

7. The display apparatus of claim 6 , wherein a curvature radius of the outer side surface is different from that of the inner side surface.

8. The display apparatus of claim 7 , wherein the curvature radius of the outer side surface is greater than that of the inner side surface.

9. The display apparatus of claim 6 , wherein the first curved surface of the first substrate, the outer side surface of the sealing element, and the second curved surface of the second substrate form a substantially continuous curved surface.

10. The display apparatus of claim 1 , wherein the first curved surface is curved in a first direction from the first outer surface to the first inner surface such that a vertex of the first curved surface is adjacent to the sealing element.

11. A display apparatus comprising:
a first substrate comprising a first inner surface and a first outer surface opposite to the first inner surface;
a display element on the first inner surface of the first substrate;
a second substrate comprising a second inner surface facing the first inner surface and a second outer surface opposite to the second inner surface; and
a sealing element located between the first and second substrates, and surrounding the display element; and
wherein the second substrate further comprises a second side surface comprising a second curved surface with respect to a direction from the first outer surface to the second outer surface and a second flat surface extending from the second curved surface toward the second outer surface in the direction from the first outer surface to the second outer surface.

12. The display apparatus of claim 11 , wherein the sealing element comprises an inner side surface toward the display element and an outer side surface opposite to the inner side surface, and the outer side surface is adjacent to a vertex of the second curved surface.

13. The display apparatus of claim 12 , wherein the curvature radius of the outer side surface is greater than that of the inner side surface.

14. The display apparatus of claim 12 , wherein the first substrate further comprises a first side surface connecting the first inner surface and the first outer surface, the first side surface comprising a first curved surface, and
the second substrate comprises the second side surface connecting the second inner surface and the second outer surface.

15. The display apparatus of claim 14 , wherein the first curved surface is curved in a first direction from the first outer surface to the first inner surface such that a vertex of the first curved surface is adjacent to the sealing element.

16. The display apparatus of claim 14 , wherein the second curved surface is curved in a second direction from the second outer surface to the second inner surface such that a vertex of the second curved surface is adjacent to the sealing element.

17. The display apparatus of claim 14 , wherein the first side surface further comprises a first flat surface between the first outer surface and the first curved surface.

18. The display apparatus of claim 14 , wherein the first curved surface of the first substrate, the outer side surface of the sealing element, and the second curved surface of the second substrate form a curved surface of the display apparatus.

19. The display apparatus of claim 18 , wherein the curved surface of the display apparatus is a substantially continuous curved surface.

20. The display apparatus of claim 11 , further comprising a touch screen conductive pattern on the second substrate.
