Abstract

A display panel includes: a substrate including a component area and a main area surrounding at least a portion of the component area, the component area including a pixel area and a transmission area; a display element layer on the substrate, the display element layer including a first display element overlapping the pixel area of the component area in a plan view, a second display element overlapping the pixel area of the component area, and a pixel defining layer defining therein a first opening and a second opening defining an emission area of the first display element and an emission area of the second display element, respectively; and an anti-reflective layer on the display element layer, the anti-reflective layer including a black matrix defining therein a first upper opening overlapping the first opening and the second opening, and a first color filter overlapping the first upper opening.

First claim

What is claimed is:

1. An electronic device comprising:
a housing having a rear surface and a side surface;
a cover window on the housing;
a display panel below the cover window; and
a component between the housing and the display panel,
wherein the display panel comprises:
a substrate comprising a component area and a main area surrounding at least a portion of the component area, wherein the component area comprises a pixel area, a transmission area, a bridge area, an overlap area, and a non-overlap area;
a display element layer on the substrate, wherein the display element layer comprises a first display element overlapping the pixel area in the plan view, and a pixel defining layer defining therein a first opening, and the first opening defines therein an emission area of the first display element; and
an anti-reflective layer on the display element layer, wherein the anti-reflective layer comprises a black matrix defining therein a first upper opening overlapping the first opening in the plan view,

wherein the pixel defining layer and the black matrix overlap each other in the overlap area in the plan view.

2. The electronic device of claim 1 , wherein the overlap area is between the main area and the transmission area.

3. The electronic device of claim 1 , wherein the non-overlap area is between the overlap area and the transmission area.

4. The electronic device of claim 3 , wherein the transmission area includes an inner transmission area and an outer transmission area, and
wherein the outer transmission area is between the main area and the inner transmission area.

5. The electronic device of claim 4 , wherein the non-overlap area is between the overlap area and the outer transmission area.

6. The electronic device of claim 1 , wherein only one of the pixel defining layer and the black matrix is disposed in the non-overlapping area.

7. The electronic device of claim 1 , wherein at least one of the pixel defining layer and the black matrix is disposed in the bridge area.

8. The electronic device of claim 1 , wherein the display element layer further comprises a second display element overlapping the pixel area in the plan view, and
wherein the pixel defining layer defines therein a second opening and the second opening defines therein an emission area of the second display element.

9. The electronic device of claim 8 , wherein the first upper opening of the black matrix overlaps the second opening in the plan view.

10. The electronic device of claim 8 , wherein anti-reflective layer further comprises a first color filter overlapping the first upper opening in the plan view.

11. A display panel comprising:
a substrate comprising a component area and a main area surrounding at least a portion of the component area, wherein the component area comprises a pixel area, a transmission area, a bridge area, an overlap area, and a non-overlap area;
a display element layer on the substrate, wherein the display element layer comprises a first display element overlapping the pixel area in a plan view and a pixel defining layer defining therein a first opening, and the first opening defines an emission area of the first display element; and
an anti-reflective layer on the display element layer, wherein the anti-reflective layer comprises a black matrix defining therein a first upper opening overlapping the first opening in the plan view,
wherein the pixel defining layer and the black matrix overlap each other in the overlap area in the plan view.

12. The display panel of claim 11 , wherein the overlap area is between the main area and the transmission area.

13. The display panel of claim 11 , wherein the non-overlap area is between the overlap area and the transmission area.

14. The display panel of claim 13 , wherein the transmission area includes an inner transmission area and an outer transmission area, and
wherein the outer transmission area is between the main area and the inner transmission area.

15. The display panel of claim 14 , wherein the non-overlap area is between the overlap area and the outer transmission area.

16. The display panel of claim 11 , wherein only one of the pixel defining layer and the black matrix is disposed in the non-overlapping area.

17. The display panel of claim 11 , wherein at least one of the pixel defining layer and the black matrix is disposed in the bridge area.

18. The display panel of claim 11 , wherein the display element layer further comprises a second display element overlapping the pixel area in the plan view, and
wherein the pixel defining layer defines therein a second opening and the second opening defines therein an emission area of the second display element.

19. The display panel of claim 18 , wherein the first upper opening of the black matrix overlaps the second opening in the plan view.

20. The display panel of claim 18 , wherein the anti-reflective layer further comprises a first color filter overlapping the first upper opening in the plan view.
