Abstract

A display apparatus includes a substrate including a display area, a camera hole, and a non-display area between the display area and the camera hole, at least one cut-out part and at least one dam disposed in the non-display area, a plurality of insulating films disposed on the substrate and disposed under a light-emitting element, the cut-out part, and the dam, and a crack detection unit disposed between the at least one cut-out part and the camera hole.

Claims (27)

1 . A display apparatus comprising:

a substrate including a display area, a camera hole, and a non-display area between the display area and the camera hole;

at least one cut-out part and at least one dam disposed in the non-display area;

a plurality of insulating films disposed on the substrate and disposed under a light-emitting element, the cut-out part, and the at least one dam; and

a crack detection unit disposed between the at least one cut-out part and the camera hole,

wherein the crack detection unit comprises a crack detection line and a connection line, and

wherein the connection line is disposed under the at least one cut-out part and the at least one dam to overlap with the at least one cut-out part and the at least one dam.

2 . The display apparatus of claim 1 , wherein the plurality of insulating films comprise a gate insulating film, a first interlayer insulating film and a second interlayer insulating film.

3 . The display apparatus of claim 2 , wherein the crack detection line is disposed in an area where a portion of the first interlayer insulating film or the second interlayer insulating film is removed.

4 . The display apparatus of claim 2 , wherein the connection line is disposed between the gate insulating film and the first interlayer insulating film.

5 . The display apparatus of claim 1 , wherein the crack detection line has a circular planar shape excluding a partial section thereof.

6 . The display apparatus of claim 5 , wherein the connection line is in electrical contact with the crack detection line.

7 . The display apparatus of claim 6 , wherein the connection line extends to be perpendicular to the crack detection line, the at least one cut-out part and the at least one dam.

8 . A display apparatus comprising:

a substrate including a non-display area disposed between a camera hole and a display area;

one or more cut-out parts and at least one dam disposed in the non-display area;

a touch sensor unit disposed to correspond to the display area;

a touch crack detection electrode disposed to correspond to the non-display area; and

a crack detection unit disposed to correspond to the non-display area,

wherein the crack detection unit comprises a crack detection line and a connection line, and

wherein the connection line is disposed under the one or more cut-out parts and the at least one dam to overlap with the one or more cut-out parts and the at least one dam.

9 . The display apparatus of claim 8 , wherein the crack detection line and the touch crack detection electrode do not overlap with each other; and

wherein the connection line and the touch crack detection electrode are disposed to overlap with each other.

10 . The display apparatus of claim 8 ,

wherein the crack detection line is disposed between the one or more cut-out parts.

11 . The display apparatus of claim 9 , further comprising a pack layer disposed between the connection line and the touch crack detection electrode.

12 . The display apparatus of claim 11 , further comprising a crack detection pad electrically connected to the connection line in the non-display area.
