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; and
a sealing element located between the first and second substrates, and surrounding the display element;
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 flat surface and a first curved surface.

2. The display apparatus of claim 1 , wherein the first flat surface extends from the first curved surface toward the first outer surface in a direction from the first inner surface to the first outer surface.

3. The display apparatus of claim 2 , 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.

4. The display apparatus of claim 1 , 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.

5. The display apparatus of claim 1 , 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 flat surface.

6. The display apparatus of claim 1 , 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.

7. The display apparatus of claim 6 , 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.

8. The display apparatus of claim 6 , wherein the second side surface further comprises a second flat surface.

9. The display apparatus of claim 8 , wherein the second flat surface extends from the second curved surface toward the second outer surface in a direction from the second inner surface to the second outer surface.

10. The display apparatus of claim 8 , wherein 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.

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

12. The display apparatus of claim 11 , further comprising a plurality of line patterns overlapping the sealing element.
