1. A display panel comprising:
an upper display substrate comprising a first pixel area, a second pixel area, a third pixel area, and a light-blocking area around the first pixel area, the second pixel area, and the third pixel area; and
a lower display substrate comprising a first display element, a second display element, and a third display element that correspond to the first pixel area, the second pixel area, and the third pixel area, respectively,
wherein the upper display substrate comprises:
a base substrate;
a first color filter on the base substrate and overlapping the first pixel area;
a second color filter on the base substrate, overlapping the second pixel area, and to allow light different in wavelength from that of the first color filter to pass therethrough;
a third color filter on the base substrate, overlapping the light-blocking area and the third pixel area, having a first opening and a second opening that correspond to the first pixel area and the second pixel area, respectively, and to allow light different in wavelength from those of the first color filter and the second color filter to pass therethrough; and
a fourth color filter on the base substrate, overlapping the light-blocking area, the first pixel area, and the second pixel area, having a third opening corresponding to the third pixel area, and to allow light different in wavelength from that of the third color filter to pass therethrough, and
wherein the fourth color filter is adjacent to the first color filter, the second color filter, and the third color filter in the light-blocking area between first pixel area and the second pixel area.
