Abstract
An organic light-emitting display device includes a substrate; a switching thin-film transistor on the substrate; a driving thin-film transistor connected to the switching thin-film transistor; and a light-emitting element connected to the driving thin-film transistor, wherein the switching thin-film transistor and the driving thin-film transistor together include: a lower conductive layer on the substrate; an insulation layer having therein a contact hole configured to expose the lower conductive layer; an upper conductive layer connected to the lower conductive layer through the contact hole; and a mask conductive layer between an upper surface of the insulation layer and the upper conductive layer to overlap the upper conductive layer.
