Display device including an adhesive layer

1. A display device comprising:

a display panel having a display area and a non-display area;

a window disposed on the display panel;

a bezel portion disposed on the window, the bezel portion at least partially overlapping the non-display area;

an adhesive layer disposed between the display panel and the window; and

an interlayer disposed between the bezel portion and the adhesive layer,

wherein the interlayer has at least one ultrasound transmitting area overlapping the bezel portion, and

wherein the ultrasound transmitting area does not overlap a conductor in the space between the window and the adhesive layer.

2. The display device as claimed in claim 1 , wherein the at least one ultrasound transmitting area is a substantially circular through hole.

3. The display device as claimed in claim 2 , wherein the through hole has a diameter in a range of about 100 μm to about 300 μm.

4. The display device as claimed in claim 1 , further comprising a touch panel disposed between the window and the adhesive layer.

5. The display device as claimed in claim 4 , wherein the touch panel is connected to the interlayer.

6. The display device as claimed in claim 1 , wherein the interlayer does not overlap the display area, and the interlayer forms a closed loop along an edge of the window.

7. The display device as claimed in claim 1 , wherein the interlayer is electrically conductive.

8. The display device as claimed in claim 1 , wherein the interlayer comprises a metal or a transparent conductive oxide (TCO).

9. The display device as claimed in claim 1 , wherein the at least one ultrasound transmitting area does not overlap a conductor in a space between the window and the adhesive layer.

10. The display device as claimed in claim 1 , wherein the adhesive layer includes a photo-curable adhesive.

11. The display device as claimed in claim 1 , wherein at least a portion of the adhesive layer is disposed within a space defined by the at least one ultrasound transmitting area.

12. The display device as claimed in claim 1 , wherein the adhesive layer contacts the bezel portion through the at least one ultrasound transmitting area.

13. The display device as claimed in claim 1 , wherein the interlayer includes a base portion overlapped by the bezel portion, and wherein the base portion of the interlayer includes the at least one ultrasound transmitting area configured to transmit ultrasonic waves to a greater extent than the base portion.

14. The display device as claimed in claim 1 , Wherein the display panel further comprises:

a first substrate;

a second substrate opposing the first substrate; and

a liquid crystal layer disposed between the first substrate and the second substrate.

15. The display device as claimed in claim 1 , wherein the display panel further comprises:

a first substrate;

a first electrode disposed on the first substrate;

an organic light emitting layer disposed on the first electrode; and

a second electrode disposed on the organic light emitting layer.

16. The display device as claimed in claim 1 , wherein the at least one ultrasound transmitting area is a concave portion and the concave portion at least partially overlaps the bezel portion.

17. The display device as claimed in claim 16 , wherein the interlayer at least partially surrounds the display area on a plane.

18. The display device as claimed in claim 17 , wherein the concave portion is open in a direction toward the display area.

19. The display device as claimed in claim 16 , wherein the concave portion does not overlap a conductor in a space between the window and the adhesive layer.

20. The display device as claimed in claim 16 , wherein the concave portion has a diameter in a range of about 100 μm to about 300 μm.
