Abstract: A display panel includes an emission area and a non-emission area. A light emitting element includes a first electrode, an emission layer on the first electrode, and a second electrode on the emission layer. A pixel defining layer includes a first opening defined therein and exposing the first electrode. A first encapsulation layer is on the second electrode to overlap the light emitting element. The first encapsulation layer includes a first inorganic layer on the second electrode and a second inorganic layer on the first inorganic layer. A top surface of the second electrode overlaps the first opening and includes at least one first stepped portion. A bottom surface of the second inorganic layer directly contacts a top surface of the first inorganic layer. At least one of the top surface of the first inorganic layer or a top surface of the second inorganic layer is a flat surface.
