More Information
Summary:A touch display device includes a shield electrode disposed between a touch electrode and a display electrode, by not disposing the touch electrode and the shield electrode on a part of an area overlapping with a data line, thus direct and indirect coupling by the data line can be reduced and a crosstalk by a coupling between a touch signal and a display signal can be reduced. Furthermore, in the case that the shield electrode is disposed on a layer where a connecting pattern connecting between the touch electrode and the touch line is disposed, by maintaining an arrangement of the shield electrode on some area where the data line is overlapped and the touch electrode isn't disposed, thus an effect of a coupling reduction can be provided while maintaining a noise blocking performance of the shield electrode stably.
