Abstract

A display device includes a display panel, a touch sensor on the display panel, a window on the touch sensor, an adhesive layer between the window and the touch sensor, a touch key printed circuit board at least partially located between the window and the display panel, a touch key backlight unit on the touch key printed circuit board, and a shielding layer between the touch key printed circuit board and the display panel.

Claims (40)

1. A display device comprising:

a display panel;

a touch sensor on the display panel;

a window on the touch sensor;

an adhesive layer between the window and the touch sensor;

a touch key printed circuit board at least partially located between the window and the display panel;

a touch key backlight unit on the touch key printed circuit board; and

a shielding layer between the touch key printed circuit board and the display panel, wherein the shielding layer does not contact the display panel.

2. The display device of claim 1 , further comprising an adhesive member between the shielding layer and the touch key printed circuit board.

3. The display device of claim 1 , wherein the shielding layer comprises polyethylene terephthalate.

4. The display device of claim 1 , further comprising a cover tape on the shielding layer and on the touch key backlight unit.

5. The display device of claim 1 , wherein the touch key backlight unit comprises:

a light source;

a light guide plate configured to receive light emitted from the light source on one surface thereof and to emit the light through the opposite surface thereof;

an optical sheet on the light guide plate; and

a reflective sheet under the light guide plate.

6. The display device of claim 1 , wherein the shielding layer is thicker than the adhesive layer.

7. The display device of claim 1 , further comprising a polarizer between the display panel and the window.

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

a first substrate comprising a display area and a non-display area;

a second substrate opposite the first substrate; and

a display unit between the first and second substrates.

9. The display device of claim 8 , wherein the display unit comprises any one of a liquid crystal and an organic light emitting element.

10. The display device of claim 8 , wherein the touch sensor is patterned on the second substrate.

11. The display device of claim 8 , wherein the touch sensor is located on the second substrate.

12. The display device of claim 1 , wherein the shielding layer is directly coupled to the touch key printed circuit board by an adhesive.

13. A display device comprising:

a display panel;

a touch sensor on the display panel;

a window on the touch sensor;

an adhesive layer between the window and the touch sensor;

a touch key printed circuit board at least partially located between the window and the display panel;

a touch key backlight unit on the touch key printed circuit board; and

a shielding layer between the touch key printed circuit board and the display panel;

wherein the touch key backlight unit comprises:

a light source;

a light guide plate configured to receive light emitted from the light source on one surface thereof and to emit the light through the opposite surface thereof;

an optical sheet on the light guide plate; and

a reflective sheet under the light guide plate;

wherein the shielding layer is longer than the light guide plate.
