Abstract

A display device includes a display panel including a substrate including a front display region, a side display region extending from a side of the front display region, and a transmission region including at least a portion overlapping the front display region in a plan view; and a sensor located on a bottom of the substrate, the sensor having at least a portion overlapping the transmission region in a plan view. The display panel includes first pixels in the front display region; a load compensation element in the side display region; and a connection line electrically connecting the first pixels and the load compensation element by detouring the transmission region.

Claims (77)

1. A display device comprising:

a display panel including a substrate including:

a front display region;

a side display region extending from a side of the front display region at a bending line that forms a curved surface; and

a transmission region including at least a portion overlapping the front display region in a plan view; and

a sensor located on a bottom of the substrate, the sensor having at least a portion overlapping the transmission region in a plan view,

wherein the display panel includes:

first pixels disposed in the front display region;

third pixels and a load compensation element disposed in the side display region; and

a connection line electrically connecting the first pixels and the load compensation element by detouring the transmission region.

2. The display device of claim 1 , wherein

the front display region includes a first region, a second region, and a third region, the first region, the second region, and the third region having different areas, and

the connection line electrically connects first pixels disposed in the second region and first pixels disposed in the third region by detouring the transmission region.

3. The display device of claim 2 , wherein an area of the first region is greater than an area of the second region and an area of the third region.

4. The display device of claim 2 , wherein the load compensation element compensates for a difference between a load value of the second region and the third region and a load value of the first region.

5. The display device of claim 2 , wherein the first pixels of the second region, that are electrically connected to a side of the connection line, and the first pixels of the third region, that are electrically connected to another side of the connection line, are disposed on a same pixel row.

6. The display device of claim 5 , wherein the load compensation element is a dummy pixel that does not emit light.

7. The display device of claim 5 , wherein the connection line includes bent parts.

8. The display device of claim 5 , wherein the side display region includes:

a first side display region extending from a first side of the front display region; and

a second side display region extending from a second side of the front display region, wherein

the display panel includes a corner region disposed between the first side display region and the second side display region.

9. A display device comprising:

a display panel including a substrate including:

a front display region;

a side display region extending from a side of the front display region; and

a transmission region including at least a portion overlapping the front display region in a plan view; and

a sensor located on a bottom of the substrate, the sensor having at least a portion overlapping the transmission region in a plan view,

wherein the display panel includes:

first pixels disposed in the front display region;

a load compensation element disposed in the side display region, the load compensation element including a first conductive layer, a semiconductor layer, and a second conductive layer that are stacked; and

a connection line electrically connecting the first pixels and the load compensation element by detouring the transmission region, wherein

the first conductive layer and the second conductive layer are electrically connected to each other to form a first capacitor electrode of the load compensation element, and

the semiconductor layer forms a second capacitor electrode of the load compensation element.

10. The display device of claim 9 , wherein the connection line is formed of a same conductive layer as the first conductive layer.

11. A display device comprising:

a display panel including a substrate including:

a front display region;

a side display region extending from a side of the front display region; and

a transmission region including at least a portion overlapping the front display region in a plan view; and

a sensor located on a bottom of the substrate, the sensor having at least a portion overlapping the transmission region in a plan view,

wherein the display panel includes:

first pixels disposed in the front display region,

a load compensation element disposed in the side display region; and

a connection line electrically connecting the first pixels and the load compensation element by detouring the transmission region, wherein

the display panel includes:

a substrate;

a circuit element layer disposed on the substrate, the circuit element layer including transistors;

a first electrode electrically connected to the transistors;

a second electrode disposed on the first electrode; and

a light emitting layer disposed between the first electrode and the second electrode, wherein

the load compensation element is a dummy pixel that does not emit light, and

at least one of the first electrode, the second electrode, and the light emitting layer does not overlap the dummy pixel.

12. A display device comprising:

a display panel including a substrate including:

a front display region,

a side display region extending from a side of the front display region; and

a transmission region including at least a portion overlapping the front display region in a plan view; and

a sensor located on a bottom of the substrate, the sensor having at least a portion overlapping the transmission region in a plan view,

wherein the display panel includes:

first pixels disposed in the front display region;

a load compensation element disposed in the side display region; and

a connection line electrically connecting the first pixels and the load compensation element by detouring the transmission region, wherein

the display panel includes second pixels disposed in the transmission region.

13. The display device of claim 12 , wherein a number of first pixels per unit area is greater than a number of second pixels per unit area.

14. The display device of claim 12 , wherein

the transmission region includes a transmission part not overlapping the second pixels, and

the sensor overlaps the transmission part.

15. The display device of claim 14 , wherein the second pixels are adjacent to the transmission part.

16. The display device of claim 14 , wherein the sensor is a camera and receives light from the transmission part while overlapping the transmission part.

17. The display device of claim 16 , further comprising:

a reflective member that reflects light from the transmission part and transfers the reflected light to the sensor.

18. The display device of claim 14 , wherein the display panel includes a first signal line electrically connected to the first pixels disposed on a same pixel row or a same pixel column by detouring the transmission part.

19. The display device of claim 18 , wherein the first signal line and the connection line are formed of different conductive layers.
