Abstract
There is disclosed a shift register comprising a bootstrap circuit that outputs a voltage of the supply voltage to the output when the voltage of a first node becomes higher or lower than the supply voltage. The shift register comprises: two or more transistors connected in series to the first node; a device for supplying the voltage to a second node between the transistors such that the voltage between the drains and sources of the transistors becomes below the supply voltage; a first input transistor connected to the first node, and the gate electrode thereof is connected to a first input terminal as well; and an output transistor connected to the output terminal and the clock signal while having the gate electrode connected to the first node, wherein the gate electrode of the output transistor is not opened except for the bootstrap period.
