ABSTRACT:
In a liquid crystal display device of the in-plane switching mode (IPS mode), the potential of data that is output from a data driver is set at values between potentials that are given to common lines. Two levels, i.e., high and low levels, are prepared for the potential to be given to the common lines and the potential is inverted between those levels in every field, whereby the polarity of a voltage between both electrodes of a pixel is inverted. As a result, the potential variation ranges of signals that are output from the data driver and a scan driver can be greatly reduced from those of the conventional case, which contributes to reduction in the power consumption of the drivers. Since the voltage applied to a switching element for controlling each pixel can be reduced, the load of the switching element can also be reduced.
