Abstract
The present invention relates to an organic light-emitting display device having excellent efficiency due to improved luminance. To this end, the present invention provides an organic light-emitting display device comprising: a substrate; a plurality of thin-film transistors formed on each of a plurality of pixel areas defined by the intersection of a plurality of gate lines and data lines formed on the substrate; a plurality of organic light-emitting devices formed on the upper surfaces of the thin-film transistors and electrically connected to the respective thin-film transistors; a black matrix layer formed between the adjacent organic light-emitting devices; and a multilayered coating film coated on the surface of the black matrix layer and formed of the lamination of substances that have different refractive indices from each other.
