Abstract: According to an aspect, a display device includes: a display unit that has a plurality of scanning signal lines to which a scanning signal is applied; a shift register that has a plurality of transfer circuits configured in a plurality of stages that perform a shift operation for temporarily storing a shift signal that has been input and sequentially transmitting the stored shift signal to a subsequent stage in synchronization with a clock signal having a discontinued period, and outputs the scanning signal to a scanning signal line corresponding to a transfer circuit that maintains the shift signal; and a signal line that transmits a holding potential signal for maintaining a potential of the shift signal to a transfer circuit that maintains the shift signal in the discontinued period of the clock signal.
