Abstract: An organic light-emitting display device characterized by improved reliability is disclosed. The organic light-emitting display device is configured such that each of an organic encapsulation layer, which is disposed on a light-emitting element, and an upper inorganic encapsulation layer, which is disposed on the organic encapsulation layer, are divided into a plurality of parts. Even when cracks are formed in a subpixel due to an external impact or when external moisture or oxygen permeates into the subpixel, therefore, it is possible to prevent the cracks, the moisture, or the oxygen from diffusing to an adjacent subpixel, whereby the reliability and lifespan of the display device are improved.
