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.
