Abstract
A display device includes a pixel defining film on a substrate with openings in which light emitting elements are disposed, a capping layer on a common electrode of the light emitting elements, an auxiliary layer on the capping layer and including bismuth, a thin film encapsulation layer including first to third encapsulation layers, a light blocking layer disposed on the thin film encapsulation layer with opening holes overlapping the openings, and an antireflection layer on the light blocking layer. The first encapsulation layer includes first to third inorganic insulating layers including silicon oxynitride. The capping layer and the first to third inorganic insulating layers have different thicknesses or refractive indices from each other. A first opening interval between a first opening and a first opening hole overlapping the first opening is greater than a second opening interval between a second opening and a second opening hole overlapping the second opening.
