Abstract

A display device includes a display panel that includes a substrate, a display layer disposed on the substrate, and a thin-film encapsulation layer that covers the display layer; an input sensing member that includes a base layer and sensing electrodes disposed on the base layer, wherein the base layer faces the substrate of the display panel; and a resin layer disposed between the thin-film encapsulation layer and the base laver. The display device includes an opening area and a display area that at least partially surrounds the opening area. A side surface of the substrate that at least partially surrounds the opening area has a shape in a thickness direction of the substrate that differs from a shape in the thickness direction of a side surface of another part of the substrate.

First claim

What is claimed is:

1. A display device, comprising:
a display panel that includes a substrate, a display layer disposed on the substrate, and a thin-film encapsulation layer that covers the display layer;

a resin layer disposed between the thin-film encapsulation layer and the base layer, wherein
the display device includes an opening area and a display area that at least partially surrounds the opening area, and
a side surface of the substrate that at least partially surrounds the opening area includes a portion having a rounded shape in a first cross-sectional view of the substrate that differs from a rounded shape in a second cross-sectional view of a side surface of another part of the substrate.

2. The display device of claim 1 , wherein the resin layer includes an ultraviolet (UV) curable material.

3. The display device of claim 1 , wherein the resin layer extends toward an edge of the substrate beyond an edge of the thin-film encapsulation layer.

4. The display device of claim 1 , wherein the thin-film encapsulation layer includes at least one inorganic encapsulation layer and at least one organic encapsulation layer.

5. The display device of claim 1 , wherein the input sensing member includes
a first conductive layer,
a second conductive layer disposed on the first conductive layer, and

6. The display device of claim 5 , wherein the first conductive layer is in direct contact with the base layer.

7. The display device of claim 1 , wherein
a side surface of the base layer that at least partially surrounds the opening area includes a portion having a rounded shape in the first cross-sectional view of the base layer that differs from a rounded shape in the second cross-sectional view of a side surface of another part of the base layer.

8. The display device of claim 1 , wherein a side surface of the resin layer forms a continuous surface with side surfaces of the substrate and the base layer.

9. The display device of claim 1 , wherein a side surface of the resin layer is spaced inward toward the display layer from side surfaces of the substrate and the base layer.

10. A display device, comprising:
a substrate that includes a first inner surface and a first outer surface that is opposite to the first inner surface;

11. The display device of claim 10 , wherein the resin layer is transparent and includes a ultraviolet (UV) curable resin.

12. The display device of claim 10 , wherein the resin layer extends toward an edge of the substrate and an edge of the base layer beyond an edge of the thin-film encapsulation layer.

13. The display device of claim 10 , further comprising a sensor layer positioned on the base layer and that includes first sensing electrodes and second sensing electrodes.

14. The display device of claim 10 , wherein
the substrate includes a first side surface that at least partially surrounds the opening area and a second side surface that differs from the first side surface, and
the first side surface has a shape in a thickness direction of the substrate that differs from that of the second side surface.

15. The display device of claim 14 , wherein
the first side surface of the substrate includes a first inclined surface adjacent to the first outer surface of the substrate, and
the third side surface of the base layer includes a second inclined surface adjacent to the second outer surface of the base layer.

16. The display device of claim 14 , wherein
the second side surface of the substrate comprises a first curved surface adjacent to the first inner surface of the substrate, and
the fourth side surface of the base layer comprises a second curved surface adjacent to the second inner surface of the base layer.

17. The display device of claim 15 , wherein a side surface of the resin layer forms a continuous surface with the first side surface and the second side surface.

18. The display device of claim 15 , wherein a side surface of the resin layer forms a continuous surface with the third side surface and the fourth side surface or
