1. A display panel comprising:
a substrate comprising a main display area, a component area, and a peripheral area;
an inorganic insulating layer overlapping a surface of the substrate and comprising a terraced opening overlapping the component area;
a buffer layer disposed between the inorganic insulating layer and the substrate;
a first organic insulating layer filling the terraced opening in the inorganic insulating layer; and
an auxiliary light emitting display element overlapping both the first organic insulating layer and the component area, wherein
the inorganic insulating layer comprises a first insulating layer having a first opening, a second insulating layer having a second opening, and a third insulating layer having a third opening,
the first opening in the first insulating layer, the second opening in the second insulating layer, and the third opening in the third insulating layer overlap each other and form corresponding portions of the terraced opening in the inorganic insulating layer, an area of the first opening is less than an area of the second opening, and
the first insulating layer is positioned nearer to the substrate than the second insulating layer.
