Abstract

Embodiments of the present disclosure provide a display device comprising: a substrate; a thin film transistor layer on a first surface of the substrate and including a first hole; a light emitting element layer on the thin film transistor layer and including a light emitting element; a first light blocking layer between the substrate and the thin film transistor layer and including a second hole overlapping the first hole in a thickness direction of the substrate; and a second light blocking layer between the thin film transistor layer and the light emitting element layer and including a third hole overlapping the first hole and the second hole in the thickness direction of the substrate.

Claims (51)

1. A display device, comprising:

a substrate;

a first layer on a first surface of the substrate;

a first insulating film on the first layer;

a second layer on the first insulating film;

a second insulating film on the second layer;

an anode electrode on the second insulating film;

a light emitting layer on the anode electrode;

a cathode electrode on the light emitting layer,

wherein an area in which the first layer and the second layer do not overlap with each other is defined,

wherein the area comprises a first portion parallel to a first direction and a second portion parallel to a second direction,

wherein the second layer comprises a scan line, and

wherein at least a portion of the scan line extends in the first direction.

2. The display device of claim 1 , wherein the first layer comprises an active layer of a transistor, and

wherein the second layer comprises a gate electrode of the transistor.

3. The display device of claim 2 , further comprising:

a third layer disposed on the first surface of the substrate; and

a third insulating film disposed on the third layer,

wherein the first layer is disposed on the third insulating film.

4. The display device of claim 3 , wherein the first layer, the second layer and the third layer do not overlap with each other in the area.

5. The display device of claim 4 , wherein the third layer overlaps the active layer of the transistor.

6. The display device of claim 2 , further comprising:

a fourth layer disposed on the second insulating film; and

a fourth insulating film disposed on the fourth layer,

wherein the anode electrode is disposed on the fourth insulating film.

7. The display device of claim 6 , wherein the first layer, the second layer and the fourth layer do not overlap with each other in the area.

8. The display device of claim 7 , wherein the fourth layer comprises a connection electrode, and

wherein the anode electrode is connected to the connection electrode through a contact hole penetrating the fourth insulating film.

9. The display device of claim 1 , wherein the first layer comprises a source region or a drain region, and

wherein at least a portion of the source region or the drain region extends in the second direction.

10. The display device of claim 1 , wherein the area further comprises a third portion parallel to a third direction which is a different from the first direction and the second direction.

11. The display device of claim 10 , wherein the third direction is a diagonal direction against the first direction and the second direction.

12. The display device of claim 1 , further comprising:

a sensor disposed on a second surface of the substrate to detect light incident through the area.

13. The display device of claim 12 , wherein the sensor comprises a sensor pixel overlapping the area in a thickness direction of the substrate.

14. The display device of claim 1 , further comprising:

an encapsulation layer disposed on the cathode electrode; and

a plurality of sensor electrodes disposed on the encapsulation layer,

wherein the first layer, the second layer and the plurality of sensor electrodes do not overlap with each other in the area.

15. A display device, comprising:

a substrate;

a first layer on a first surface of the substrate;

a first insulating film on the first layer;

a second layer on the first insulating film;

a second insulating film on the second layer;

an anode electrode on the second insulating film;

a light emitting layer on the anode electrode;

a cathode electrode on the light emitting layer,

wherein an area in which the first layer and the second layer do not overlap with each other is defined,

wherein the area comprises a first portion parallel to a first direction and a second portion parallel to a second direction, and

wherein a first maximum length of the area in the first direction is smaller than a second maximum length of the area in the second direction.
