    Abstract: A display panel includes a light-emitting element disposed on a base substrate and including a light-emitting layer, an inorganic deposition layer disposed on the light-emitting element, and an encapsulation layer disposed on the inorganic deposition layer. The inorganic deposition layer includes a first portion including a first upper surface inclined at a first angle with respect to an upper surface of the base substrate, and a second portion including a second upper surface substantially parallel to the upper surface of the base substrate. A first thickness of the first portion is greater than a second thickness of the second portion. Accordingly, external light reflection may be reduced, and a layer uniformity may be improved, and thus the display device may have improved display efficiency.
