    摘要： 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.

    摘要： A touch display device includes a touch sensing electrode and a touch drive electrode disposed on an encapsulation unit configured to encapsulate a light-emitting element, the touch sensing electrode and the touch drive electrode being configured to form a first mutual capacitor, and first and second compensation electrodes disposed in a non-active area of a substrate so as to be opposite each other, the first and second compensation electrodes being configured to form a second mutual capacitor, whereby the value of capacitance of all mutual capacitors is increased, and therefore it is possible to prevent deterioration in touch performance.
