    Abstract: A display panel includes a base layer that includes a display area and a non-display area adjacent to the display area, a plurality of emission elements on the display area, and an encapsulation layer that includes an organic layer and an inorganic layer in contact with a bottom surface of the organic layer. The organic layer may be on the plurality of emission elements. The inorganic layer may include an oxygen atom and a silicon atom. In the inorganic layer, a top surface of a portion that overlaps the display area and a top surface of a portion that overlaps the non-display area have a substantially identical surface roughness.
