Abstract: The plurality of stages of circuit blocks of a driver circuit in a display device include a first transistor and a second transistor. The first transistor is connected at its gate with a first node and controls conductivity between a scanning signal line and a first clock signal line applied with a first clock signal. The first node is at an active potential when at least any one signal of signals output from one stage in each of a forward direction and a reverse direction is at the active potential. The second transistor is connected at its gate with the first node and controls conductivity between the first clock signal line and an input signal line of another stage of circuit block.
