Abstract: An organic light-emitting display apparatus is disclosed. In one embodiment, the display apparatus includes i) a substrate and ii) an organic light-emitting device formed on the substrate, the organic light-emitting device including a stack structure including a first electrode, an organic light-emitting layer, and a second electrode. The apparatus may further include a sealing layer formed on the substrate so as to cover the organic light-emitting device, the sealing layer including an inorganic layer and a porous layer interposed between the sealing layer and the organic light-emitting device. One embodiment can reduce a stress due to a sealing inorganic layer so as to maintain characteristics for a long time in a severe environment and not affect an organic light-emitting device.
