Abstract
Each shift register includes a first element controlled by a first potential node to supply a first driving voltage to an output terminal, a second element controlled by a second potential node to supply a second driving voltage lower than the first driving voltage to the output terminal, and a third element for controlling the first potential node and the second potential node so as to have opposite potential levels. Voltages are applied to the third element so that a state of A>B and A>C and a state of A<B and A<C, or a state of A>B and A<C and a state of A<B and A>C, or a state of A<B and A>C and a state of A>B and A<C are switched alternately (A: a gate terminal of the third element, B: a voltage applied to a first terminal thereof, C: a voltage applied to a second terminal thereof).
