An object is to enhance the driving capability and improve the operating speed of a unit shift register applicable to a scanning line driving circuit having a partial display function. A unit shift register forming a gate line driving circuit includes a first transistor that supplies a first clock signal to a first output terminal, a second transistor that supplies a second clock signal to a second output terminal, a third transistor that charges the gate of the first transistor in response to activation of a shift signal of the previous stage, and a fourth transistor connected between the gate of the first transistor and the gate of the second transistor. The first clock signal and the second clock signal have the same phase, and only the second clock signal is activated in a particular period (a display ineffective period).
