(154) formed between a gate electrode and an output elec trode of a TFT (152), the electric potential of the gate elec trode 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
