Abstract
A display panel includes an upper display substrate. The upper display substrate includes a base substrate and first to fourth color filters. The first and second color filters overlap first and second pixel areas. The third color filter overlaps a light-blocking area and a third pixel area and has a first opening and a second opening corresponding to the first pixel area and second pixel area, respectively. The fourth color filter overlaps the first pixel area and the second pixel area and has a third opening corresponding to the third pixel area.
