Display device and method of manufacturing display device
A display device includes: 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.
1. A method of manufacturing a display device, the method comprising:
preparing a first substrate in which a first through hole is formed;
forming an inorganic insulating layer on the first substrate;
forming a display element layer on the inorganic insulating layer, the display element layer including a display element;
preparing a second substrate in which a second through hole is formed;
aligning the first substrate and the second substrate such that the first through hole corresponds to the second through hole; and
forming a blocking member along an inner surface of the first through hole and an inner surface of the second through hole.
2. The method of claim 1 , wherein the inorganic insulating layer extends from the display area to the inner surface of the first through hole.
3. The method of claim 2 , wherein the blocking member covers the inorganic insulating layer extending to the inner surface of the first through hole.
4. The method of claim 1 , wherein the forming of the display element layer includes:
forming an inorganic encapsulation layer on the display element layer,
wherein the inorganic encapsulation layer extends from the display area to the inner surface of the first through hole.
5. The method of claim 1 , further comprising:
forming an optical functional layer on the second substrate, the optical functional layer including a third through hole connected to the second through hole;
forming an adhesive layer on the optical functional layer, the adhesive layer including a fourth through hole connected to the third through hole; and
arranging a cover window on the adhesive layer, the cover window covering the display area and the fourth through hole.
6. The method of claim 5 , wherein a size of the fourth through hole is greater than a size of the third through hole, and
the blocking member extends from the inner surface of the second through hole to an upper surface of the optical functional layer.
7. The method of claim 1 , further comprising arranging a component such that the component passes through the first through hole and the second through hole.
