Accordingly, the parasitic capacitance formed between shield pattern SP and the data lines DL has no indirect effect on the touch electrodes TE or touch lines TL, and thus, crosstalk occurring in the touch sensing signals may be reduced.

In this case, a load caused by the application of the shield signal may also be reduced, compared to the case in which the common voltage Vcom is applied to the shield pattern SP through the touch electrodes TE, since the shield signal is applied to the shield pattern SP through the shield lines SL.

FIG. 10 is a view illustrating another example structure of applying a shield signal to the shield pattern in the touch display device according to embodiments, in which the shield pattern and the backlight shield pattern are connected through independent shield lines and the shield signal is applied to the shield pattern through independent shield lines.

Referring to FIG. 10, in the touch display device 100 according to embodiments, the shield pattern SP is disposed between the touch lines TL and the data lines DL while overlapping the data lines DL. In an area in which the shield pattern SP does not overlap the touch lines TL or the data lines DL, the shield pattern SP and the backlight shield pattern BLSP may be connected through independent shield lines SL and the shield signal may be applied to the shield pattern SP through the shield lines SL.
