Abstract
To a unit circuit, provided are a transistor to which a first clock signal is supplied, a transistor for applying an off-level voltage to a first node, a transistor for applying the off-level voltage to a second node, a transistor for applying an on-level voltage to the second node based on a clock signal being ahead of the first clock signal in a forward direction scanning, a transistor for applying the on-level voltage to the second node based on a clock signal being ahead of the first clock signal in a backward direction scanning, and a circuit for controlling a voltage of the first node based on output signals of the unit circuits in a front-side stage and a back-side stage. The unit circuit is configured so that a voltage of the second node is changed to an ON level and an OFF level while a voltage of the first node is in the OFF level and the voltage of the second node is in the ON level when the first clock signal is changed to the ON level while the voltage of the first node is in the OFF level.
