Abstract: A display device is provided. The display device includes a plurality of pixels; a first base; an organic light emitting element on the first base and in each of the pixels; a second base facing the first base; and a filling pattern layer between the organic light emitting elements and the second base, the filling pattern layer including a first pattern portion and a second pattern portion alternately arranged along a same direction in a plan view, wherein the first pattern portion is in each of the pixels, the second pattern portion is at a boundary of each of the pixels and contacts the first pattern portion, and a refractive index of the second pattern portion is smaller than that of the first pattern portion.
