Abstract: A display panel includes a substrate including first, second, and third emission areas, an organic insulating layer on the substrate, first, second, and third pixel electrodes on the organic insulating layer, a pixel-defining layer in which first, second, and third openings, and an out-gassing hole are defined. The first, second, and third openings extend to at least a portion of each of the first, second, and third pixel electrodes. First, second, and third emission layers are respectively on the first, second, and third pixel electrodes. The out-gassing hole includes first, second, and third out-gassing holes defined around the first, second, and third openings. An area of the first out-gassing hole is greater than areas of the second and third out-gassing holes.
