Touch display device
Provided is a touch display device. Because a shielding electrode, which is disposed in a non-active area and electrically coupled between a common electrode and a common voltage supply line, is located between a touch routing line and a signal line, the effects of noise caused by the signal line on the touch routing line may be reduced. Further, an encapsulation portion located on the shielding electrode has a planarized structure. The resulting maintenance of a certain distance between the shielding electrode and the touch routing line may reduce noise caused by the signal line from indirectly affecting the touch routing line through the shielding electrode.
