Abstract: A display panel includes: a base layer; a pixel-defining layer disposed on the base layer and defining first to third emission-openings therein; first to third pixels each including a first electrode, a second electrode, and a light-emitting pattern between the first electrode and the second electrode, which are disposed in a corresponding emission-opening; a partition wall, which is disposed on the pixel-defining layer and in which first to third partition wall-openings corresponding to the first to third emission-openings are defined, respectively; and an encapsulation layer including a lower inorganic layer, an upper inorganic layer, and an organic layer. The lower inorganic layer includes first to third inorganic layers covering the first to third pixels, respectively, and the first to third inorganic layers are spaced apart from each other on the partition wall and have different thicknesses from each other.

Abstract: A display device includes a display element layer including a first electrode layer, a light-emitting layer disposed on the first electrode layer, and a second electrode layer disposed on the light-emitting layer, a capping layer disposed on the second electrode layer, a protective layer disposed on the capping layer and covering a portion of the second electrode layer exposed by the capping layer, an optical compensation layer disposed on the protective layer, and an encapsulation layer disposed on the optical compensation layer. The refractive index of the optical compensation layer is lower than that of the protective layer.
