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.

Abstract: Various embodiments provide a thin and lightweight organic light-emitting display device having a touch sensor. The organic light-emitting display device having a touch sensor includes a touch-sensing line and a touch-driving line disposed on an encapsulation stack so as to overlap each other. The touch-sensing line and the touch-driving line overlap each other in a location in which an organic touch dielectric film and an inorganic touch dielectric film are disposed therebetween, thereby preventing the generation of spots in the event of degeneration of the organic touch dielectric film and preventing damage to the organic touch dielectric film.
