Abstract

A display apparatus including a substrate including a display area and a sensor area, the sensor area including a transmission portion that transmits light, a plurality of first display devices arranged in the display area, a display device group including a plurality of second display devices, the display device group being arranged in the sensor area, and a passivation layer covering the display device group and having a first hole corresponding to the transmission portion.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate comprising a display area and a sensor area, the sensor area comprising a transmission portion that transmits light;
a plurality of first display devices arranged in the display area;
a display device group comprising a plurality of second display devices, the display device group being arranged in the sensor area; and
a passivation layer covering the display device group and having a first hole corresponding to the transmission portion,
wherein the plurality of second display devices comprises a pixel electrode, an emission layer on the pixel electrode, and an opposite electrode on the emission layer, the opposite electrode having a second hole corresponding to the transmission portion, and an area of the second hole being greater than an area of the first hole.

2. The display apparatus of claim 1 ,
wherein the passivation layer is on the opposite electrode.

3. The display apparatus of claim 2 ,
wherein the passivation layer covers the display device group and has first patterns spaced from each other with the first hole between the first patterns,
wherein the opposite electrode corresponds to the display device group and has second patterns spaced from each other with the second hole between the first patterns, and
wherein an end of one of the first patterns on a side of the first hole covers an end of one of the second patterns on a side of the second hole.

4. The display apparatus of claim 1 , further comprising:
an organic insulating layer between the substrate and the pixel electrode; and
a pixel defining layer between the organic insulating layer and the opposite electrode and having an opening that exposes at least a portion of the pixel electrode.

5. The display apparatus of claim 4 ,
wherein the pixel defining layer has a third hole corresponding to the transmission portion, and
wherein the organic insulating layer has a fourth hole corresponding to the transmission portion.

6. The display apparatus of claim 5 , further comprising a plurality of insulating layers between the substrate and the organic insulating layer,
wherein the plurality of insulating layers are below the fourth hole and has a fifth hole corresponding to the transmission portion.

7. The display apparatus of claim 1 , further comprising an encapsulation layer on the passivation layer, the encapsulation layer covering the plurality of first display devices and the plurality of second display devices and comprising an inorganic encapsulation layer and an organic encapsulation layer.

8. The display apparatus of claim 7 , wherein the passivation layer comprises a same material as the inorganic encapsulation layer.

9. The display apparatus of claim 1 , further comprising an encapsulation substrate on the passivation layer, the encapsulation substrate covering the plurality of first display devices and the plurality of second display devices and opposite the substrate.

10. The display apparatus of claim 9 , further comprising a filling material filled between the passivation layer and the encapsulation substrate,
wherein the filling material has a refractive index between a refractive index of the passivation layer and a refractive index of the encapsulation substrate.

11. A display apparatus comprising:
a substrate comprising a display area and a sensor area, the sensor area comprising a transmission portion that transmits light;
a plurality of first display devices arranged in the display area;
a display device group comprising a plurality of second display devices, the display device group being arranged in the sensor area; and
a passivation layer covering the display device group and having a first hole corresponding to the transmission portion,
wherein the substrate further comprises an opening area surrounded by the display area, and
wherein the opening area comprises a hole having a larger size than the transmission portion.

12. A display apparatus comprising:
a substrate comprising a display area and a sensor area, the sensor area comprising a plurality of transmission portions that transmits light;
a plurality of first display devices arranged in the display area;
a plurality of second display devices arranged in the sensor area;
an opposite electrode integrally included in the plurality of first display devices and a plurality of second display devices; and
a passivation layer on the opposite electrode and having a plurality of first holes, wherein each of the plurality of first holes corresponds to one of the plurality of transmission portions,
wherein the opposite electrode having a plurality of second holes, wherein each of the plurality of second holes corresponds to one of the plurality of transmission portions.

13. The display apparatus of claim 12 , wherein a display resolution of the sensor area is lower than a display resolution of the display area.

14. The display apparatus of claim 12 , further comprising a buffer layer on the substrate, the buffer layer is disposed corresponding to the plurality of transmission portions.

15. The display apparatus of claim 12 , further comprising an organic insulating layer between the substrate and the plurality of second display devices, wherein the organic insulating layer has a fourth hole corresponding to one of the transmission portions.

16. The display apparatus of claim 12 , further comprising an encapsulation layer on the passivation layer, the encapsulation layer covering the plurality of first display devices and the plurality of second display devices and comprising an inorganic encapsulation layer and an organic encapsulation layer.

17. The display apparatus of claim 16 , wherein the passivation layer comprises a same material as the inorganic encapsulation layer.
