Here, the shield signal applied to the shield pattern SP and the backlight shield pattern BLSP may be a signal, the voltage and phase of which are the same as those of the touch driving signal TDS applied to the touch electrodes TE during the touch sensing periods, or a signal, the voltage and phase of which are the same as those of the common voltage Vcom applied to the pixel electrode PE during the display driving periods. Alternatively, the shield signal may be a signal, the voltage and phase of which are different from those of either the touch driving signal TDS or the common voltage Vcom.

Since the shield pattern SP has the shield signal applied thereto through the shield lines SL as described above, even in the case in which parasitic capacitance is formed between the shield pattern SP and the data lines DL, the effect of the parasitic capacitance formed between the shield pattern SP and the data lines DL may be reduced by relatively larger capacitance formed in the shield pattern SP through the shield lines SL.

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 and the shield pattern SP are in electrical contact with each other.
