Abstract: A display panel may include a first display substrate and a second display substrate on the first display substrate. The second display substrate may include a plurality of pixel regions and a peripheral region adjacent to the pixel regions. The second display substrate may include a first color control pattern configured to emit light of a first color, a second color control pattern spaced apart from the first color control pattern in a first direction and configured to emit light of a second color different from the first color, and first and second light-blocking patterns in the peripheral region between the first and second color control patterns. The first and second light-blocking patterns may be spaced apart from each other, in a second direction crossing the first direction, to define a gap region.
