摘要:
The present invention provides a liquid crystal display device where a common driver circuit formed of only a single channel transistor can be made smaller, wherein the counter electrode driving circuit has M basic circuits that are connected to M counter electrodes (M≧2), the (n−1)th selection scan signal, the nth selection scan signal, an alternating current signal and an inverse alternating current signal are inputted in the nth basic circuit (1≦n≦M), there is a difference in phase between said selection scan signal and said alternating current signal, as well as between said selection scan signal and said inverse alternating current signal, and said nth basic circuit supplies a positive or negative counter voltage to the Nth counter electrode on the basis of said inputted (n−1)th selection scan signal, nth selection scan signal, alternating current signal and inverse alternating current signal.
