Display device and method of manufacturing display device

1. A display device comprising:

a first substrate including a first through hole, a display area, and a non-display area, the display area surrounding the first through hole, and the non-display area surrounding at least a portion of the display area;

an inorganic insulating layer arranged in the display area;

a display element layer including a display element and arranged on the inorganic insulating layer;

a second substrate including a second through hole and arranged on the display element layer, the second through hole being connected to the first through hole; and

a blocking member arranged along an inner surface of the first through hole and the second through hole, and extending from the first substrate to the second substrate,

wherein the inorganic insulating layer extends from the display area to the inner surface of the first through hole.

2. The display device of claim 1 , wherein the display element includes a pixel electrode and an opposite electrode, and

the opposite electrode extends from the display area to the inner surface of the first through hole.

3. The display device of claim 2 , wherein the display element layer further includes an organic insulating layer arranged between the inorganic insulating layer and the opposite electrode, and

the inorganic insulating layer contacts the opposite electrode on the inner surface of the first through hole.

4. The display device of claim 1 , further comprising an inorganic encapsulation layer covering the display element,

wherein the inorganic encapsulation layer extends from the display area to the inner surface of the first through hole.

5. The display device of claim 1 , further comprising an optical functional layer disposed on the second substrate and including a third through hole connected to the second through hole,

wherein the blocking member extends from the second substrate to the optical functional layer.

6. The display device of claim 5 , further comprising:

a cover window disposed on the optical functional layer and covering the display area and the third through hole; and

an adhesive layer arranged between the optical functional layer and the cover window and including a fourth through hole connected to the third through hole.

7. The display device of claim 6 , wherein a size of the fourth through hole is greater than a size of the third through hole, and

the blocking member extends to an upper surface of the optical functional layer.

8. The display device of claim 1 , wherein the blocking member includes a black pigment.

9. The display device of claim 1 , wherein the blocking member includes a moisture-proof insulating material.

10. The display device of claim 1 , wherein the blocking member covers the inorganic insulating layer extending to the inner surface of the first through hole.

11. The display device of claim 1 , wherein at least one of the first substrate and the second substrate includes glass.

12. The display device of claim 1 , further comprising a component arranged to pass through the first through hole and the second through hole.

13. The display device of claim 12 , further comprising:

an optical functional layer disposed on the second substrate and including a third through hole connected to the second through hole; and

a cover window disposed on the optical functional layer and covering the display area and the third through hole,

wherein the component is arranged to pass through the third through hole.
