Abstract

A display device can include a display panel including a non-display area and a display area. The display area can include a first area, a third area surrounded by the first area, and a second area disposed between the first area and the third area. Here, at least one of the first, second, and third area can include a plurality of light emitting areas and a plurality of transmission areas. The display device can further include an optical electronic device located under, or in a lower portion of, the display panel and overlapping at least a portion of the first area included in the display area. The display panel can include a light shield layer disposed under transistors in the plurality of light emitting areas and not disposed in the plurality of transmission areas.

Claims (25)

1. A display device comprising:

a display panel comprising a display area comprising a first area and a third area surrounded by the first area, wherein the third area comprises a plurality of light emitting areas and a plurality of transmission areas; and

an optical electronic device disposed under, or in a lower portion of, the display panel and overlapping at least a portion of the third area included in the display area,

wherein the display panel comprises a light shield layer disposed under transistors in the plurality of light emitting areas and not disposed in the plurality of transmission areas.

2. The display device according to claim 1 , wherein the display area further comprises a second area disposed between the first area and the third area,

the display panel further comprises a non-display area adjacent to the display area, and

the light shield layer is disposed in an entire area of the second area.

3. The display device according to claim 2 , wherein the light shield layer is continuously disposed from the second area to the third area.

4. The display device according to claim 2 , wherein: the first area corresponds to a first resolution,

the second area corresponds to a second resolution lower than the first resolution, and

the third area corresponds to a third resolution lower than the second resolution.

5. The display device according to claim 1 , wherein each of a plurality of subpixels disposed in the display area includes a driving transistor and at least one scan transistor.

6. The display device according to claim 5 , wherein each of the at least one scan transistor is an oxide thin film transistor.

7. The display device according to claim 5 , wherein the light shield layer is disposed under the driving transistor in the first area.

8. The display device according to claim 1 , wherein the third area comprises a first optical area and a second optical area, and

wherein a first optical electronic device is disposed under the first optical area, and a second optical electronic device is disposed under the second optical area.

9. The display device according to claim 8 , wherein the first optical electronic device includes a camera.

10. The display device according to claim 8 , wherein the second optical electronic device includes a sensor.

11. The display device according to claim 2 , wherein the display panel further comprises a cathode electrode disposed in the plurality of light emitting areas included in the first area, the second area, and the third area, and not disposed in the plurality of transmission areas in the third area.

12. The display device according to claim 1 , wherein each of the plurality of transmission areas has a circular, elliptical, or polygonal shape.

13. The display device according to claim 1 , wherein the third area has a circular, elliptical, or polygonal shape.

14. The display device according to claim 2 , wherein the second area has a circular, elliptical, or polygonal shape to surround the third area.

15. The display device according to claim 1 , wherein an area of each of the plurality of light emitting area is smaller than an area of each of the plurality of transmission areas.

16. The display device according to claim 8 , wherein at least one layer included in the display panel has depression in the plurality of transmission areas.

17. The display device according to claim 8 , wherein a transmittance of the first optical area is greater than a transmittance of the second optical area.
