Abstract: An organic light-emitting display device having a touch sensor is discussed. The organic light-emitting display device includes a touch sensor formed in a single-layer structure and disposed on 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 uppermost layer of the encapsulation unit, thereby simplifying the structure thereof and reducing costs.

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.

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: A touch display device includes a unit pixel disposed on a substrate, the unit pixel comprising a plurality of subpixels; a light-emitting element disposed at each of the plurality of subpixels; an encapsulation unit disposed on the light-emitting element; a plurality of touch electrodes disposed on the encapsulation unit; a touch line connected to each of the plurality of touch electrodes, the touch line extending through the touch electrode; and at least one redundant electrode spaced apart from the touch electrode, the redundant electrode being independently disposed in each of the plurality of touch electrodes, the redundant electrode being disposed in the unit pixel. The redundant electrode is disposed along the touch line, whereby it is possible to reduce parasitic capacitance formed between the touch line and the touch electrode.
