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.
