The invention provides an active matrix type TFT LCD in which a driving voltage of pixel TFTs is reduced. A pixel is formed with two thin film transistors, i.e., a positive-voltage-applying n-channel TFT for applying a data voltage having a positive polarity to a pixel electrode and a negative-voltage-applying p-channel TFT for applying a data voltage having a negative polarity to the pixel electrode. A source electrode of the positive-voltage-applying TFT is connected to the pixel electrode; a drain electrode of the same is connected to a data bus line for applying the positive voltage; and a gate electrode of the same is connected to a gate bus line for applying the positive voltage. A source electrode of the other TFT is also connected to the pixel electrode; a drain electrode of the same is connected to a data bus line for applying the negative voltage; and a gate electrode of the same is connected to a gate bus line for applying the negative voltage.
