Abstract

A display device includes: an electronic module; and an electronic panel including: a first area overlapping the electronic module; a second area surrounding at least a portion of the first area in a plan view; and an indicia disposed on the first area.

Claims (76)

1. A display device comprising:

a camera; and

an electronic panel including:

a first area overlapping the camera;

a second area surrounding at least a portion of the first area in a plan view;

an indicia disposed in the first area; and

a light blocking layer, wherein:

the first area comprises a panel module area including a central area, a pattern area surrounding the central area and a line area surrounding the pattern area,

the second area comprises an active area,

the line area comprises a hole signal line providing an electrical signal,

the indicia comprises an alignment mark disposed in the pattern area,

the alignment mark and the hole signal line disposed on a same layer, and

the light blocking layer overlaps the alignment mark and the hole signal line in a plan view.

2. The display device of claim 1 , wherein the electronic panel further comprises:

a base layer;

a plurality of pixels disposed in the active area on the base layer; and

an encapsulation layer disposed on the base layer to cover the pixels,

wherein the alignment mark is disposed on the encapsulation layer.

3. The display device of claim 1 , wherein the electronic panel further comprises:

a base layer;

a plurality of pixels disposed on the active area on the base layer;

an encapsulation layer disposed on the base layer to cover the pixels; and

an input sensing layer disposed on the encapsulation layer and comprising a plurality of sensing patterns and a plurality of sensing insulation layers disposed between the sensing patterns.

4. The display device of claim 3 , wherein the alignment mark and one of the plurality of sensing patterns are disposed on a same layer.

5. The display device of claim 3 , wherein the plurality of sensing insulation layers comprise a first sensing insulation layer and a second sensing insulation layer, and

the alignment mark is disposed between the first sensing insulation layer and the second sensing insulation layer.

6. The display device of claim 3 , wherein the encapsulation layer comprises:

a first inorganic layer;

a second inorganic layer disposed on the first inorganic layer; and

an organic layer disposed between the first inorganic layer and the second inorganic layer,

wherein the first inorganic layer does not overlap the central area.

7. The display device of claim 6 , wherein the second inorganic layer overlaps the central area.

8. The display device of claim 7 , wherein the second inorganic layer has a light transmittance greater than that of the first inorganic layer.

9. The display device of claim 3 , further comprising a window disposed on the encapsulation layer,

wherein the window comprises a window substrate including a window module area overlapping the panel module area in a plan view, and

wherein the light blocking layer disposed on the window module area on one surface of the window substrate.

10. The display device of claim 9 , wherein the window module area comprises:

a transmission area overlapping the central area in a plan view; and

a light blocking pattern area surrounding the transmission area,

wherein the light blocking layer is disposed on the light blocking pattern area.

11. The display device of claim 10 , wherein the light blocking pattern area overlaps the pattern area in a plan view.

12. The display device of claim 1 , wherein the electronic panel further comprises:

a base layer;

an insulation layer disposed on the base layer;

a plurality of pixels disposed on the active area on the base layer; and

an encapsulation layer disposed on the base layer to cover the pixels,

wherein the alignment mark is disposed between the insulation layer and the encapsulation layer.

13. The display device of claim 1 , wherein the indicia has conductivity.

14. The display device of claim 1 , wherein the indicia is optically opaque.

15. A display device comprising:

a camera; and

an electronic panel that is divided into a first area overlapping the camera and second area surrounding at least a portion of the first area in a plan view,

wherein the electronic panel comprises:

a plurality of pixels disposed on the second area;

an encapsulation layer configured to cover the pixels;

an indicia disposed on the encapsulation layer overlapping the first area in a plan view, and

a light blocking layer,

wherein the first area comprises a panel module area including a central area, a pattern area surrounding the central area and a line area surrounding the pattern area,

the second area comprises an active area,

the line area comprises a hole signal line providing an electrical signal,

the indicia comprises an alignment mark disposed in the pattern area,

the alignment mark and the hole signal line disposed on a same layer, and

the light blocking layer overlaps the alignment mark and hole signal line in a plan view.

16. The display device of claim 15 , wherein the encapsulation layer comprises:

a first inorganic layer;

a second inorganic layer disposed on the first inorganic layer; and

an organic layer disposed between the first inorganic layer and the second inorganic layer,

wherein the first inorganic layer does not overlap the central area, and the second inorganic layer overlaps the central area.

17. The display device of claim 15 , further comprising a window disposed on the encapsulation layer,

wherein the window comprises:

a window substrate comprising a window module area overlapping the panel module area in a plan view; and

wherein the light blocking layer disposed on the window module area on one surface of the window substrate.

18. The display device of claim 17 , wherein the window module area comprises:

a transmission area overlapping the central area in a plan view; and

a light blocking pattern area surrounding the transmission area,

wherein the light blocking layer is disposed on the light blocking pattern area.
