Abstract
The present disclosure provides a touch display device having a structure in which at least one touch electrode is disposed on an encapsulation layer, and including a noise shielding layer located between a layer in which the signal line under the encapsulation layer is disposed and a layer in which at least one light emitting element is disposed. The noise shielding layer can block coupling between the signal line and an electrode of the light emitting element, and reduce or 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.
