Abstract

A display apparatus includes: a substrate having a first display area, a second display area, a third display area between the first display area and the second display area, and a non-display area; a first connection pixel circuit in the first display area; a second connection pixel circuit in the second display area; a driver circuit in the third display area; a signal connection line connected to a first contact portion of the first connection pixel circuit and a second contact portion of the second connection pixel circuit and extending in a first direction to pass the third display area; and an inorganic insulating layer comprising a first groove between the driver circuit and at least any one of the first contact portion and the second contact portion, the first groove extending in a second direction and crossing the signal connection line in a plan view.

Claims (43)

1. A display apparatus comprising:

a substrate having a first display area, a second display area, a third display area between the first display area and the second display area, and a non-display area;

a first connection pixel circuit in the first display area;

a second connection pixel circuit in the second display area;

a driver circuit in the third display area;

a signal connection line extending only partially into the first display area to be connected to a first contact portion of the first connection pixel circuit and extending only partially into the second display area to be connected to a second contact portion of the second connection pixel circuit and extending in a first direction to pass through an entirety of the third display area along the first direction; and

an inorganic insulating layer comprising a first groove between the driver circuit and at least any one of the first contact portion and the second contact portion, the first groove extending in a second direction and crossing the signal connection line in a plan view.

2. The display apparatus of claim 1 , further comprising an organic insulating layer, at least a portion of which is buried in the first groove.

3. The display apparatus of claim 2 , wherein a dielectric constant of the organic insulating layer is less than or equal to 3.5.

4. The display apparatus of claim 2 , further comprising:

a connection electrode above the organic insulating layer; and

a display element above the connection electrode and comprising a pixel electrode, an emission layer, and an opposite electrode,

wherein at least a portion of the emission layer overlaps the driver circuit.

5. The display apparatus of claim 1 , wherein the inorganic insulating layer further comprises a second groove extending in the second direction and in parallel with the first groove with the first contact portion or the second contact portion therebetween.

6. The display apparatus of claim 1 , wherein the first contact portion is on an edge portion of the first connection pixel circuit that is adjacent to the driver circuit, and

the second contact portion is on an edge portion of the second connection pixel circuit that is adjacent to the driver circuit.

7. The display apparatus of claim 1 , wherein the signal connection line bypasses the driver circuit.

8. The display apparatus of claim 7 , wherein the signal connection line is provided in plural, and

the inorganic insulating layer further comprises a third groove between two adjacent signal connection lines among the plurality of signal connection lines.

9. The display apparatus of claim 7 , wherein the inorganic insulating layer further comprises a fourth groove between the signal connection line and the driver circuit, the fourth groove extending in the first direction.

10. The display apparatus of claim 1 , wherein the first display area, the third display area, and the second display area are arranged in the first direction.

11. A display apparatus comprising:

a substrate having a first display area, a second display area, a third display area between the first display area and the second display area, and a non-display area;

a first connection pixel circuit in the first display area and comprising a first contact portion adjacent to the third display area;

a second connection pixel circuit in the second display area and comprising a second contact portion adjacent to the third display area;

a driver circuit in the third display area;

a signal connection line extending in a first direction only partially into the first display area and having an end connected to the first contact portion and extending only partially into the second display area and having another end connected to the second contact portion and extending across an entirety of the third display area along the first direction;

an inorganic insulating layer comprising a plurality of grooves; and

an organic insulating layer filling the plurality of grooves,

wherein a first groove among the plurality of grooves extends in a second direction crossing the first direction and is between the driver circuit and the first contact portion and between the driver circuit and the second contact portion.

12. The display apparatus of claim 11 , wherein the signal connection line crosses the third display area and bypasses the driver circuit.

13. The display apparatus of claim 11 , wherein the signal connection line crosses the first groove in a plan view.

14. The display apparatus of claim 11 , wherein a dielectric constant of the organic insulating layer is less than or equal to 3.5.

15. The display apparatus of claim 11 , further comprising:

a connection electrode above the organic insulating layer; and

a display element above the connection electrode and comprising a pixel electrode, an emission layer, and an opposite electrode,

wherein at least a portion of the emission layer overlaps the driver circuit in a plan view.

16. The display apparatus of claim 11 , wherein the plurality of grooves further comprise a second groove extending in the second direction and in parallel with the first groove with the first contact portion or the second contact portion therebetween.

17. The display apparatus of claim 11 , wherein the signal connection line is provided in plural, and

the plurality of grooves further comprise a third groove between two adjacent signal connection lines among the plurality of signal connection lines.

18. The display apparatus of claim 17 , wherein the plurality of grooves further comprise a fourth groove between the signal connection line and the driver circuit, the fourth groove extending in the first direction.

19. The display apparatus of claim 18 , wherein a distance from an upper surface of the substrate to a lower surface of each of the third groove and the fourth groove is less than or equal to a distance from the upper surface of the substrate to a lower surface of the signal connection line.

20. The display apparatus of claim 11 , wherein the first display area, the third display area, and the second display area are arranged in the first direction.
