Abstract

A display device includes: a display panel configured for displaying an image; at least one panel attached to the display panel; an adhesive layer formed between the display panel and the at least one panel and configured to attach the at least one panel to the display panel; a plurality of print layers formed on an outer circumferential surface of the at least one panel to block light transmitted through the adhesive layer; and a plurality of bubble outlets formed in at least one of the plurality of print layers to discharge bubbles included in the adhesive layer.

First claim

What is claimed is:

1. A display device comprising:
a display panel for displaying an image;
at least one panel attached to the display panel;
an adhesive layer between the display panel and the at least one panel to attach the at least one panel to the display panel;
a plurality of print layers around an outer circumferential surface of the at least one panel, the plurality of print layers including a first print layer and a second print layer,
wherein the second print layer includes a plurality of bubble outlets having a width narrower than a width between adjacent bubble outlets of the plurality of bubble outlets.

2. The display device of claim 1 ,
wherein the first print layer is disposed around the outer circumference of the at least one panel, and
wherein the second print layer is disposed around an outer circumference of the first print layer.

3. The display device of claim 2 , wherein the plurality of bubble outlets are configured to discharge bubbles included in the adhesive layer on the first print layer.

4. The display device of claim 1 , wherein the plurality of print layers are formed of a black resin to block light transmitted through a corresponding region.

5. The display device of claim 1 , wherein the plurality of print layers are formed of a color resin to show a corresponding region with a corresponding color.

6. The display device of claim 1 , wherein the adhesive layer is formed of an optically clear resin (OCR) or an optically clear adhesive (OCA).

7. The display device of claim 1 , wherein the at least one panel includes a cover substrate.

8. The display device of claim 7 , wherein the cover substrate is formed of glass or plastic.

9. The display device of claim 1 , wherein the at least one panel includes a functional panel.

10. The display device of claim 9 , wherein the functional panel includes a three-dimensional (3D) film patterned retarder (FPR), a parallax barrier panel, and a touch panel.

11. The display device of claim 1 , wherein the at least one panel comprises:
a cover substrate; and
a functional panel.

12. The display device of claim 11 , further comprising:
a second adhesive layer attaching the cover substrate and the functional panel; and
a second plurality of print layers in an outer circumferential region between the cover substrate and the functional panel, at least one of the second plurality of print layers including a second plurality of bubble outlets.

13. The display device of claim 1 , wherein the bubble outlets are sized to discharge bubbles included in the adhesive layer during a deaerating process, and wherein the bubble outlets are sized to not discharge adhesive included in the adhesive layer during the deaerating process.

14. The display device of claim 1 , wherein a first width between an inner edge of the first print layer and an outer edge of the at least one panel is greater than a second width between an inner edge of the second print layer and the outer edge of the at least one panel.

15. The display device of claim 1 , wherein the plurality of bubble outlets are shaped as concave recesses opening toward the display panel.
