Abstract:
A liquid crystal display device, comprising:a first voltage application circuit to apply to a data line an output voltage from a data driver;a second voltage application circuit to convert the output voltage from the data driver into an inverse output voltage having a polarity opposite to that of an output voltage from the first voltage application circuit; anda third voltage application circuit to apply an auxiliary voltage to said data line,wherein, in one period of three stages, voltage applied to the data line cycles from the auxiliary voltage applied by the third voltage application circuit during a first stage of the period, to the inverse output voltage applied by the second voltage application circuit during a second stage of the period, to the output voltage applied by the first voltage application circuit during a last stage of the period, and wherein the second voltage application circuit applies the inverse output voltage to the data line in several cycles during the second stage.
