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 are disposed in the pattern area.

Claims (49)

1. A display device comprising:

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 including a conductive pattern 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;

a light blocking layer disposed in the second area, 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,

the alignment mark is disposed between the base layer and the light blocking layer, and disposed in the pattern area.

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

a pixel disposed in the active area on the base layer;

wherein the pixel includes a first electrode, a second electrode and a control layer

disposed between the first electrode and the second electrode, and

the control layer is cut off by the recessed portion in the second area.

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

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

wherein the alignment mark is disposed on the encapsulation layer.

4. The display device of claim 1 , wherein the dam portion comprises:

a first dam part; and

a second dam part,

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

5. The display device of claim 1 , wherein the electronic 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 recessed portion covered by the inorganic layer.

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

a pixel 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.

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

8. The display device of claim 6 , 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 6 , 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

wherein the electronic panel further comprises a light blocking layer 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 10 , wherein the light blocking pattern area overlaps the pattern area in a plan view.

13. The display device of claim 10 , wherein the electronic panel further comprises a hole signal line disposed in the line area and providing an electrical signal.
