Abstract: A display panel includes an upper display substrate and a lower display substrate. The upper display substrate includes a base substrate, a first partition wall on the base substrate, overlapping the light blocking area, and configured to define first, second, and third internal regions corresponding to the first, second, and third pixel areas, a second partition wall extending from the first partition wall, overlapping at least one area of the first, second, and third pixel areas, and configured to partition a region corresponding to the at least one area into partial regions, and first, second, and third color control layers respectively located in the first, second, and third internal regions.
