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.
