An active matrix type TFT LCD is provided in which a driving voltage of pixel TFTs is reduced. A pixel (P11) is formed with two thin film transistors (TFTn11, TFTp11), i.e., a positive-voltage-applying n-channel TFT (TFTn11) for applying a data voltage (Vd11) having a positive polarity to a pixel electrode (Pe) and a negative-voltage-applying p-channel TFT (TFTp11) for applying a data voltage (Vd12) having a negative polarity to the pixel electrode (Pe). A source electrode (S) of the positive-voltage-applying TFT (TFTn11) is connected to the pixel electrode (Pe) ; a drain electrode (D) of the same is connected to a data bus line (Ldll) for applying the positive voltage (Vd11); and a gate electrode (G) of the same is connected to agate bus line (Lg11) for applying the positive voltage (Vd11). A source electrode (S) of the other TFT (TFTp11) is also connected to the pixel electrode (Pe); a drain electrode (D) of the same is connected to a data bus line (Ldl2) for applying the negative voltage (Vd12) ; and a gate electrode (G) of the same is connected to a gate bus line (Vg12) for applying the negative voltage (Vd12). <IMAGE>
