Abstract

A display device includes a first area, a second area, and a bending area between the first area and the second area, a light emitting element, an inorganic layer disposed on the light emitting element, and a thin film encapsulation layer disposed on the inorganic layer. The inorganic layer includes a first inorganic pattern in the bending area.

Claims (55)

1 . A display device comprising:

a first area, a second area, and a bending area between the first area and the second area;

a light emitting element;

an inorganic layer disposed on the light emitting element; and

a thin film encapsulation layer disposed on the inorganic layer,

wherein the inorganic layer includes a first inorganic pattern in the bending area, and

wherein the first inorganic pattern includes holes spaced apart from each other.

2 . The display device of claim 1 , wherein the inorganic layer at least partially covers the light emitting element in the first area.

3 . The display device of claim 1 , wherein

the first area and the second area are spaced apart from each other in a first direction, and

the bending area extends in a second direction intersecting the first direction.

4 . The display device of claim 3 , wherein

the first area includes a first edge area extending in the second direction on an edge of the first area, and

the inorganic layer further includes a second inorganic pattern in the first edge area.

5 . The display device of claim 4 , wherein

the second area includes a second edge area extending in the second direction on an edge of the second area, and

the inorganic layer further includes a third inorganic pattern in the second edge area.

6 . The display device of claim 5 , wherein the thin film encapsulation layer contacts the first to third inorganic patterns.

7 . The display device of claim 1 , wherein the inorganic layer includes at least one of bismuth (Bi), ytterbium (Yb), nickel (Ni), cobalt (Co), beryllium (Be), vanadium (V), titanium (Ti), zirconium (Zr), tungsten (W), tantalum (Ta), and molybdenum oxide (MoO 3 ).

8 . The display device of claim 1 , wherein a refractive index of the inorganic layer is greater than or equal to about 1.0.

9 . The display device of claim 1 , wherein an extinction coefficient of the inorganic layer is less than or equal to about 4.0.

10 . A display device comprising:

a first area, a second area, and a bending area between the first area and the second area;

a light emitting element;

an inorganic layer disposed on the light emitting element; and

a thin film encapsulation layer disposed on the inorganic layer,

wherein the inorganic layer includes a first inorganic pattern in the bending area,

wherein the first area and the second area are spaced apart from each other in a first direction, and

wherein the bending area extends in a second direction intersecting the first direction,

wherein the first area includes a first edge area extending in the second direction on an edge of the first area,

wherein the inorganic layer further includes a second inorganic pattern in the first edge area,

wherein the second area includes a second edge area extending in the second direction on an edge of the second area,

wherein the inorganic layer further includes a third inorganic pattern in the second edge area, and

wherein the first to third inorganic patterns have a same pattern in a plan view.

11 . The display device of claim 10 , wherein the first inorganic pattern includes an extension and a protrusion protruding from the extension.

12 . The display device of claim 10 , wherein the first inorganic pattern includes an extension and a bent portion bent from the extension.

13 . The display device of claim 10 , wherein the first inorganic pattern includes holes spaced apart from each other.

14 . A display device comprising:

a first area and a second area spaced apart from each other in a first direction;

a bending area disposed between the first area and the second area and bendable with respect to a bending axis extending in a second direction intersecting the first direction;

a light emitting element;

an inorganic layer disposed on the light emitting element; and

a thin film encapsulation layer disposed on the inorganic layer; and

a reflection control layer disposed on the inorganic layer,

wherein the inorganic layer includes a first inorganic pattern in the bending area.

15 . The display device of claim 14 , wherein

the first area includes a first edge area extending in the second direction on an edge of the first area, and

the inorganic layer further includes a second inorganic pattern in the first edge area.

16 . The display device of claim 14 , wherein

the second area includes a second edge area extending in the second direction on an edge of the second area, and

the inorganic layer further includes a third inorganic pattern in the second edge area.

17 . The display device of claim 14 , wherein the thin film encapsulation layer contacts the first inorganic pattern.

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

a light blocking layer disposed between the inorganic layer and the reflection control layer.

19 . The display device of claim 14 , wherein the reflection control layer includes a pigment or dye.
