Abstract
Each unit circuit that constitutes each of stages of a shift register is provided with a charge supply unit including a third node whose potential becomes high level at identical timing with a first node (a node for holding an electric charge in order to output a scanning signal (output signal) at high level), and capable of supplying an electric charge to the first node throughout a period after the potential of the third node becomes high level until the scanning signal (output signal) at high level is outputted. Here, all of the unit circuits within the shift register have an identical configuration.
