Abstract
A unit circuit of a shift register includes an output transistor whose control terminal is connected to a first node, first and second set transistors, first and second reset transistors, a control signal generating circuit that generates a control signal that changes to an on level when a first clock signal changes to an on level while the potential of the first node is at an off level, and that outputs the generated control signal to the unit circuits at a preceding stage and a next stage, a transistor that applies an off-level potential to the first node based on a control signal output from the unit circuit at the preceding stage, and a transistor that applies an off-level potential to the first node based on a control signal output from the unit circuit at the next stage.
