Abstract
A display panel includes a substrate including a first area and a second area which is adjacent to the first area, an encapsulation layer including a lower pattern in the second area, an insulating layer on the first area and the second area and defining an opening exposing a side surface of the lower pattern, an upper pattern on the insulating layer, protruding toward a center of the lower pattern and having a tip overlapping the side surface of the lower pattern, and an inorganic encapsulation layer in direct contact with the lower pattern.
Claims20
A display panel comprising:
- a substrate comprising a first area including a display element layer, and a second area which is adjacent to the first area;
- and
- on the substrate:
- a lower pattern in the second area, the lower pattern comprising a center and a side surface which is spaced apart from the center;
- an insulating layer in the first area and the second area, the insulating layer including a sidewall which defines an opening in the second area which exposes the side surface of the lower pattern to outside the insulating layer;
- an upper pattern on the insulating layer and defining a tip protruding further than the sidewall of the insulating layer and toward the center of the lower pattern, the tip overlapping the side surface of the lower pattern;
- the display element layer on the insulating layer and comprising a first electrode, an emission layer and a second electrode in order from the upper pattern;
- and
- an inorganic encapsulation layer on the display element layer,
- wherein the inorganic encapsulation layer is in direct contact with the lower pattern.
