Display device and electronic apparatus

摘要

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.

1. A display device comprising:
a display unit that has a plurality of scanning signal lines to which a scanning signal is applied; a holding potential signal line that is configured to transmit a holding potential signal for maintaining a potential of a shift signal that is sequentially supplied from a scanning control unit; a shift register that is configured to have a plurality of transfer circuits in a plurality of stages perform a shift operation, the transfer circuits including
a first transfer circuit that is disposed in a stage in which the shift signal is maintained in a discontinued period of a clock signal and that is coupled with the holding potential signal line supplying the holding potential signal, the clock signal including a first clock signal and a second clock signal, anda second transfer circuit disposed in a stage in which the shift signal is not maintained in the discontinued period of the clock signal and that is not coupled with the holding potential signal line, wherein the first transfer circuit is configured to:
temporarily store the shift signal during the discontinued period which starts at a timing when the first clock signal falls after the holding potential signal rises, and which ends before the second clock signal rises, by maintaining the holding potential signal at a high level during a first period which starts at a timing when both the holding potential signal and the first clock signal rise, and which ends before the second clock signal rises;sequentially transmit the stored shift signal to a subsequent stage in synchronization with the clock signal having the discontinued period; andoutput the scanning signal to one of the scanning signal lines corresponding to the first transfer circuit upon the second clock signal rising, wherein the second transfer circuit is configured to:
sequentially transmit the shift signal to a subsequent stage in synchronization with the clock signal having the discontinued period; andoutput the scanning signal to one of the scanning signal lines corresponding to the second transfer circuit.
