Abstract

A display device includes: an electronic module; and an electronic panel including: a base layer including an upper surface having a recessed portion and a dam portion; and an alignment mark disposed on the base layer, wherein the electronic panel includes: a first area including the electronic module; a second area surrounding at least a portion of the first area in a plan view; and an active area surrounding at least a portion of the second area in a plan view, wherein: the recessed portion and the dam portion are disposed in the second area, the second area includes a pattern area surrounding the first area and a line area surrounding the pattern area, and the alignment mark includes a conductive pattern and is disposed in the pattern area.

Claims (50)

1. A display device comprising:

an electronic module; and

a display panel comprising:

a base layer;

a circuit element layer disposed on the base layer;

a light emitting element layer disposed on the circuit layer;

an encapsulation layer disposed on the light emitting element layer;

a pixel disposed between the base layer and the encapsulation layer;

a conductive pattern; and

a light blocking layer, at least a portion of which has a black color, disposed on the encapsulation layer,

wherein the display panel comprising:

a first area including the electronic module;

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

an active area surrounding at least a portion of the second area in a plan view, wherein:

the pixel includes a first electrode, a second electrode and a control layer disposed between the first electrode and the second electrode,

the control layer is cut off in the second area,

the second area includes a pattern area surrounding the first area and a line area surrounding the pattern area,

the conductive pattern is disposed in the pattern area between the base layer and the light blocking layer, and

the light blocking layer disposed in the second area overlapping the conductive pattern.

2. The display device of claim 1 , wherein the base layer comprises an upper surface having a cut off portion and a dam portion;

the cut off portion and the dam portion are disposed in the second area, and

at least one of the first electrode and the second electrode is cut off by the cut off portion.

3. The display device of claim 2 , wherein the dam portion comprises:

a first dam part; and

a second dam part,

wherein the cut off portion is disposed between the first dam part and the second dam part.

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

an inorganic layer disposed on the base layer;

an organic layer disposed on the inorganic layer; and

an upper surface of the cut off portion covered by the inorganic layer.

5. The display device of claim 1 , wherein the pixel disposed on the active area on the base layer, and

the encapsulation layer covers the pixel.

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

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.

7. The display device of claim 6 , wherein the conductive pattern and one of the plurality of sensing patterns are disposed on a same layer.

8. The display device of claim 1 , 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 first area.

9. The display device of claim 8 , wherein the second inorganic layer overlaps the first area.

10. The display device of claim 1 , further comprising a window disposed on the encapsulation layer,

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

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

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

a transmission area overlapping the first 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.

12. The display device of claim 1 , wherein the light blocking pattern area overlaps the pattern area in a plan view.

13. The display device of claim 1 , wherein the display panel further comprises a hole signal line disposed in the line area and providing an electrical signal.
