Abstract
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.
Claims16
A touch display device, comprising:
- a substrate including an active area in which a plurality of subpixels are disposed and a non-active area defined outside the active area;
- a plurality of signal lines disposed on the non-active area;
- an encapsulation portion disposed on the active area and the plurality of signal lines;
- a plurality of touch electrodes disposed on the encapsulation portion;
- a plurality of touch routing lines disposed on the non-active area, the plurality of touch routing lines electrically connected to at least one of the plurality of touch electrodes;
- and
- a shielding electrode overlapping the plurality of signal lines and the plurality of touch routing lines between the plurality of signal lines and the plurality of touch routing lines, the shielding electrode supplied with a common voltage.
