A circuit with a large load driving capability, which is structured by single polarity TFTs, is provided. With a capacitor (154) formed between a gate electrode and an output electrode of a TFT (152), the electric potential of the gate electrode of the TFT (152) is increased by a boot strap and normal output with respect to an input signal is obtained without amplitude attenuation of an output signal due to the TFT threshold value. In addition, a capacitor (155) formed between a gate electrode and an output electrode of a TFT (153) compensates for increasing the electric potential of the gate electrode of the TFT (152), and a larger load driving capability is obtained.
