Abstract: A display device having a touch sensor that enables the size of a bezel area to be reduced is disclosed. The display device is configured such that a display area is spatially divided into first and second touch areas, and first sensing-routing lines, connected to touch electrodes in the first touch area, and second sensing-routing lines, connected to touch electrodes in the second touch area, are not disposed in side and upper bezel areas but are alternately disposed in a lower bezel area. Consequently, it is possible to reduce the size of the side bezel area and the upper bezel area.

Abstract: An organic light-emitting display device having a touch sensor is discussed. The organic light-emitting display device can include a touch sensor formed in a single-layer structure and disposed on a touch insulating film overlapping an encapsulation unit disposed on a light-emitting element. First and second bridges and first and second touch electrodes included in the touch sensor having a single-layer structure are formed of the same material as each other in the same plane, e.g., on the touch insulating film, thereby simplifying the structure thereof and reducing costs.
