Abstract
An organic light-emitting display panel can improve the color purity and color gamut by reducing optical interference between adjacent pixel areas. A black bank layer is disposed on a planarization layer, such that it is possible to suppress light emitted from an organic emission layer from being reflected via various paths to be scattered to adjacent pixel areas. In addition, the black bank layer comes in contact with a color filter layer via holes formed in the planarization layer to thereby reduce optical interference between adjacent pixel areas. In this manner, the color purity and color gamut of displayed images can be improved, and a display device with excellent image quality can be implemented.
