Abstract

A display device includes an active region and a non-active region. The display device includes a display panel and a polarizing member which is disposed on a surface of the display panel, where the display panel and the polarizing member include a first through hole which penetrates the display panel and the polarizing member in a thickness direction and a hole coating layer which is disposed on an inner wall of the polarizing member of the first through hole.

Claims (28)

1. A display device including an active region and a non-active region, the display device comprising:

a display panel comprising a plurality of pixels in the active region, the display panel including a first surface, a second surface facing the first surface and a first through hole penetrating from the first surface to the second surface;

a transparent bonding layer on the first surface of the display panel; and

a window layer on the transparent bonding layer, the window layer comprises a base and a print layer defining an optical opening inside on the base,

wherein the optical opening overlaps the first through hole, and

an inner diameter of the optical opening defined in the print layer is smaller than an inner diameter of the first through hole penetrating the display panel.

2. The display device of claim 1 , wherein the transparent bonding layer includes a second through hole which overlaps the first through hole.

3. The display device of claim 2 , wherein an inner diameter of the second through hole is greater than the inner diameter of the optical opening.

4. The display device of claim 3 , wherein the inner diameter of the second through hole is smaller than the inner diameter of the first through hole.

5. The display device of claim 1 , wherein the transparent bonding layer overlaps an inner wall of the first through hole.

6. The display device of claim 5 , wherein the transparent bonding layer further overlaps an inner wall of the optical opening.

7. The display device of claim 1 , wherein the print layer covers an inner wall of the first through hole.

8. The display device of claim 1 , wherein the optical opening is surrounded by the print layer in a plan view.

9. The display device of claim 1 , wherein the first through hole and the optical opening are surrounded by the active region in a plan view.

10. The display device of claim 1 , wherein the first through hole is positioned in the non-active region.

11. The display device of claim 1 , wherein the display panel comprises:

a substrate;

a transistor on the substrate;

an insulating layer over the transistor;

a first electrode connected to the transistor;

a light emitting layer on the first electrode; and

a second electrode on the light emitting layer.

12. The display device of claim 11 , wherein the display panel further comprises a thin film encapsulation layer on the second electrode, the thin film encapsulation layer including a first inorganic layer, an organic layer on the first inorganic layer and a second inorganic layer on the organic layer.

13. The display device of claim 12 , wherein the display panel further comprises a dam structure disposed adjacent the first through hole.

14. The display device of claim 13 , wherein the dam structure includes the insulating layer.

15. The display device of claim 13 , wherein the first inorganic layer and the second inorganic layer contact with each other on the dam structure.

16. The display device of claim 12 , wherein the display panel further comprises a touch member on the thin film encapsulation layer including, the touch member including at least one touch conductive layer and at least one touch insulating layer.

17. The display device of claim 11 , wherein the substrate comprises a first sub-substrate, a second sub-substrate and a barrier layer between the first sub-substrate and the second sub-substrate.
