Abstract:
1. A scanning signal line drive circuit of a display device, that drives a plurality of scanning signal lines which are arrayed in a display unit, the circuit comprising: a shift register having a plurality of bistable circuits connected in series with each other, outputted signals from the plurality of bistable circuits being sequentially driven active based on a plurality of clock signals that are externally inputted and cyclically repeat an ON level and an OFF level, wherein each bistable circuit includes: each of the first output control switching element, the first-node turnon switching element, the first first-node turnoff switching element, the first first-output-node turnoff switching element, the first second-node turnon switching element, and the first second-node turnoff switching element is a switching element which has a first electrode, a second electrode, and a third electrode and whose conduction/non-conduction between the second electrode and the third electrode is controlled by a signal applied to the first electrode, and the following equation is satisfied, where a capacitance value of the capacitative element is C
