Abstract

A display device including a display panel for displaying an image on a front surface of the display panel; a touch sensing unit provided on the display panel to sense a touch; an insulating film covering the touch sensing unit; a first circuit board of which one end is connected to the touch sensing unit; and a polarizing layer covering the touch sensing unit and a portion of the first circuit board.

Claims (52)

1. A display device comprising:

a display panel to display an image on a front surface of the display panel;

a touch sensing unit provided on the display panel to sense a touch;

an insulating film to cover the touch sensing unit;

a first circuit board of which an end is connected to the touch sensing unit; and

a polarizing layer to cover the touch sensing unit and a portion of the first circuit board,

wherein the insulating film is spaced apart from the end of the first circuit board by 0 to 0.1 mm in plan view.

2. The display device according to claim 1 ,

further comprising an adhesive provided between the polarizing layer and the touch sensing unit and the portion of the first circuit board.

3. The display device according to claim 1 ,

wherein the touch sensing unit comprises:

a substrate;

a touch sensor provided on the substrate;

a wiring connected to the touch sensor; and

a first pad portion connected to the wiring,

wherein the insulating film covers the touch sensor and the wiring.

4. The display device according to claim 3 ,

wherein the first circuit board overlaps the first pad portion.

5. The display device according to claim 1 ,

wherein the first circuit board has flexibility, and is bent so that another end of the first circuit board is disposed on a rear surface of the display panel.

6. The display device according to claim 1 ,

further comprising a second circuit board of which an end is connected to the display panel.

7. The display device according to claim 6 ,

wherein the second circuit board has flexibility, and is bent so that another end of the second circuit board is disposed on a rear surface of the display panel.

8. The display device according to claim 1 ,

wherein the insulating film and the first circuit board are in contact with each other.

9. A display device comprising:

a display panel to display an image on a front surface of the display panel;

a touch sensing unit provided on the display panel to sense a touch;

an insulating film to cover an upper surface of the touch sensing unit;

a first circuit board having a first opening and an end which is connected to the touch sensing unit; and

a polarizing layer to cover the touch sensing unit and a portion of the first circuit board,

wherein the insulating film is spaced apart from the end of the first circuit board by 0 to 0.1 mm in plan view.

10. The display device according to claim 9 ,

further comprising an adhesive provided between the polarizing layer and the touch sensing unit and the portion of the first circuit board.

11. The display device according to claim 9 ,

further comprising a second circuit board having a second opening and an end which is connected to the display panel.

12. The display device according to claim 11 ,

wherein the first circuit board and the second circuit board have flexibility, and are bent so that another end of the first circuit board and another end of the second circuit board are disposed on a rear surface of the display panel.

13. The display device according to claim 12 ,

wherein the first opening and the second opening are provided in positions corresponding to each other.

14. The display device according to claim 9 ,

wherein the touch sensing unit comprises:

a substrate;

a touch sensor provided on the substrate;

a wiring connected to the touch sensor; and

a first pad portion connected to the wiring,

wherein the insulating film covers the touch sensor and the wiring.

15. The display device according to claim 14 ,

wherein the first circuit board overlaps the first pad portion.

16. The display device according to claim 15 ,

wherein the first circuit board comprises a second pad portion corresponding to the first pad portion.
