  • Patent number: 9336897
    Abstract: A shift register circuit comprises a first transistor connected between a clock terminal and an output terminal, a second transistor for charging a control electrode of the first transistor in response to activation of an output signal of the preceding stage, a third transistor for discharging the control electrode of the first transistor, an inverter using a control electrode of the third transistor as an output end, and a fourth transistor which discharges an input end of the inverter at power-off and is turned off after power-on. A fifth transistor which is a load element of the inverter charges the control electrode of the third transistor at power-on. It is thereby possible to initialize the respective levels of the nodes without any external initialization signal and prevent a decrease in the level change rate of the output signal in the shift register circuit.
