<p>A liquid crystal device which can reduce the deterioration of the picture quality caused by optical crosstalk. Data signals supplied to a data signal line (Sn) change within the range of the negative data voltage amplitude between a first potential (B1) and a second potential (W2) when a negative voltage is applied across a liquid crystal layer, and change within the range of the positive data voltage amplitude between a third potential (W2) and a fourth potential (B2) when a positive voltage is applied across the liquid crystal layer. The data signal line (Sn) is precharged with a negative precharging potential (PV1) or a positive precharging potential (PV2) before the data signals are supplied to the line (Sn). The positive and the negative precharging potentials are asymmetrically set with respect to the center potential (VC) of the data voltage amplitude between the first and the fourth potentials. In addition, the negative precharging potential (PC1) is set closed to the first potential (B1) than the center potential (VC1) of the positive data voltage amplitude.</p> |
