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 second substrate comprising a second inner surface facing the first inner surface and a second outer surface opposite to the second inner surface;
a display element between the first inner surface and the second inner surface, the display element comprising a light emitting diode and a thin-film transistor;
a sealing element located between the first and second substrates, and surrounding the display element; and
a touch pattern on the second outer surface;
wherein the display apparatus comprises a side surface extending between the first outer surface and the second outer surface and comprising a curved surface with respect to a direction from the first outer surface to the second outer surface.

2. The display apparatus of claim 1 , further comprising a plurality of line patterns that are disposed on the second outer surface.

3. The display apparatus of claim 2 , wherein the plurality of line patterns overlaps the sealing element.

4. The display apparatus of claim 3 , wherein the plurality of line patterns comprises a same material as the touch pattern.

5. The display apparatus of claim 1 , wherein at least one of the first substrate or the second substrate further comprises a side surface comprising a flat surface and a curved surface, the side surface of the display apparatus comprising the side surface of the at least one of the first substrate or the second substrate, and the curved surface of the side surface of the display apparatus comprising the curved surface of the side surface of the at least one of the first substrate or the second substrate.

6. The display apparatus of claim 5 , wherein a ratio of the flat surface with respect to the side surface of the at least one of the first substrate or the second substrate is less than that of the curved surface of the side surface of the at least one of the first substrate or the second substrate with respect to the side surface of the at least one of the first substrate or the second substrate.

7. The display apparatus of claim 5 , wherein the curved surface of the side surface of the at least one of the first substrate or the second substrate is curved in a first direction from the first or second outer surface to the sealing element such that a vertex of the curved surface of the side surface of the at least one of the first substrate or the second substrate is adjacent to the sealing element.

8. The display apparatus of claim 1 , 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
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.

9. The display apparatus of claim 8 , 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.

10. The display apparatus of claim 8 , 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.

11. The display apparatus of claim 8 , wherein the curved surface of the side surface of the display apparatus comprises a substantially continuous curved surface which includes the first curved surface, a side surface of the sealing element, and the second curved surface.

12. The display apparatus of claim 8 , wherein the first side surface further comprises a first flat surface, and the second side surface further comprises a second flat surface.

13. The display apparatus of claim 12 , wherein a ratio of the first flat surface with respect to the first side surface is less than that of the first curved surface with respect to the first side surface, and a ratio of the second flat surface with respect to the second side surface is less than that of the second curved surface with respect to the second side surface.
