Zusammenfassung:A touch display device includes a substrate including an active area in which a plurality of subpixels are disposed, and a non-active area located outside of the active area. A plurality of data lines are disposed over the substrate, a plurality of light emitting elements are located over the plurality of data lines where each of the plurality of light emitting elements includes an anode layer, an emission layer, and a cathode layer. An encapsulation layer is disposed on the plurality of light emitting elements and a plurality of touch electrodes are disposed on the encapsulation layer. A noise shielding layer is located between a layer in which the plurality of data lines are disposed and a layer in which the plurality of light emitting elements are disposed. The noise shielding layer may block coupling between the signal line and an electrode of the light emitting element and prevent a fluctuation in the voltage of the electrode of the light emitting element from causing noise to occur in a touch sensing signal detected by the at least one touch electrode on the encapsulation layer.
