The shift register includes a first stage having first and second transistors and a second stage having a third and fourth transistor. A voltage of a control electrode of the first transistor is boosted by a voltage of a first pulse line changing from low to high. In an On state, the second transistor connects the control electrode of the first transistor and a constant voltage line. A voltage of a control electrode of the third transistor is boosted by a voltage of a second pulse line changing from low to high. In an On state, the fourth transistor connects the control electrode of the third transistor and a constant voltage line. The fourth transistor is switched on by a signal from the first stage.
