Abstract: A display panel includes an upper display substrate including pixel areas arranged in each of pixel columns and a light blocking area and a lower display substrate including display elements respectively overlapping the pixel areas. The upper display substrate includes a base substrate, a color filter layer, and a light control layer including transmission portions overlapping first pixel areas arranged in a first pixel column and first conversion portions overlapping second pixel areas arranged in a second pixel column, and a barrier layer including first barriers disposed between the first conversion portions and the transmission portions and first sub-barriers disposed between adjacent first conversion portions. A first shortest distance from the base substrate to a lower surface of each of the first barriers is equal to a second shortest distance from the base substrate to a lower surface of each of the first sub-barriers.

Abstract: A display device including a base layer including a thin film transistor, a pixel definition layer including an opening, first to third organic light emitting elements each including a first electrode, a second electrode, and a light emitting layer therebetween, an encapsulation member including a first inorganic layer covering the organic light emitting elements, a second inorganic layer disposed thereon, a first color conversion pattern disposed between the inorganic layers and overlapping the first organic light emitting element, and a second color conversion pattern disposed between the inorganic layers and overlapping the second organic light emitting element, and first and second color filter patterns having different colors from each other and overlapping the first and second color conversion patterns, respectively, in which colors of light emitted from the first and second color conversion patterns are substantially the same as colors of the first and second color filter patterns, respectively.
