Abstract

A display apparatus includes: a substrate and a display portion on the substrate; a first treatment area including a first treatment surface on at least one side surface of the substrate; and a second treatment area adjacent the first treatment area and including a second treatment surface having a different shape from the first treatment surface of the first treatment surface.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate including a first surface, a second surface, and a third surface, the first surface being parallel to a first direction and a second direction intersecting the first direction, the second surface being opposite to the first surface, and the third surface connecting the first surface to the second surface in a third direction intersecting the first direction and the second direction;
a display portion arranged on the first surface of the substrate;
a first treatment area including a first treatment surface, the first treatment surface being arranged on the third surface of the substrate and extending in the first direction; and
a second treatment area including a second treatment surface, the second treatment surface being arranged on the third surface of the substrate, being connected to the first treatment surface in the first direction, and having a different surface shape from the first treatment surface,
wherein,
the second treatment surface includes a center treatment surface and a connection treatment surface that is closer to the first surface of the substrate than the center treatment surface, and
an angle between the connection treatment surface and the first surface is greater than an angle between an extension line of the connection treatment surface and the first surface.

2. The display apparatus of claim 1 , wherein the first treatment surface and the second treatment surface are directly connected to each other in the first direction.

3. The display apparatus of claim 1 , wherein the first treatment surface and the second treatment surface correspond to a whole thickness of the substrate.

4. The display apparatus of claim 1 , wherein the first treatment surface and the second treatment surface are formed using different treatment methods.

5. The display apparatus of claim 1 , further comprising one or more insulating layers on the substrate, wherein the first treatment surface or the second treatment surface is connected to the one or more insulating layers.

6. The display apparatus of claim 1 , further comprising one or more conductive layers on the substrate, wherein the first treatment surface or the second treatment surface is connected to the one or more conductive layers.

7. The display apparatus of claim 1 , wherein an angle between the connection treatment surface and the first surface is greater than 90 degrees.

8. The display apparatus of claim 1 , wherein a plurality of second treatment areas are formed.

9. The display apparatus of claim 8 , wherein two second treatment areas among the plurality of second treatment areas are at both sides of the first treatment area between the two second treatment areas.

10. The display apparatus of claim 1 , wherein a peripheral area is on the third surface of the substrate and does not overlap a display area of the display apparatus, and the first treatment area and the second treatment area correspond to the peripheral area.

11. The display apparatus of claim 10 , further comprising one or more pad portions in the peripheral area.

12. The display apparatus of claim 10 , wherein a wiring portion is in the peripheral area and comprises one or more wiring members.
