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.

Abstract: A display device includes a display element layer including a light emitting element and a pixel defining layer including a pixel opening, and an optical layer on the display element layer. The optical layer includes a light blocking pattern, including a first light blocking part and a second light blocking part on the first light blocking part. The first light blocking part includes a first bottom surface spaced apart from the second light blocking part and a first side surface substantially perpendicular to the first bottom surface, and the second light blocking part includes a second bottom surface adjacent to the first light blocking part and a second side surface inclined with respect to the second bottom surface. An angle between the second bottom surface and the second side surface is greater than about 90° and less than or equal to about 160°.
