Abstract
An organic light-emitting display device includes first to third color filters disposed respectively in first to third sub-pixel areas, a planarization layer disposed on the first to third color filters, and a bank layer disposed on the planarization layer and between adjacent sub-pixel areas, wherein a portion of the second color filter protrudes upwardly beyond a top face of the planarization layer, wherein the bank layer covers the portion of the second color filter protruding upwardly beyond the top face of the planarization layer. The display device has a stack structure of the portion of the blue color filter protruding upwardly beyond a top face of the planarization layer and the bank layer covering the portion, thereby suppressing light leakage between adjacent sub-pixel areas, and improving a lifetime of an organic light emitting element.
