A shift register is implemented that can switch between scanning orders of scanning signal lines, while suppressing an increase in a circuit area, an increase in current consumption, and a shortage of charge to a pixel capacitance. Each stage that constitutes a shift register (410) includes an output-control thin-film transistor for increasing a potential of a scanning signal based on a first clock (CKA), two thin-film transistors for increasing a potential of a first node connected to a gate terminal of the output-control thin-film transistor, based on a scanning signal outputted from a pre-stage/a latter stage, and two thin-film transistors for decreasing a potential of the first node, based on a scanning signal outputted from a third stage after/a third stage before a stage concerned. The shift register (410) operates based on four-phase clock signals, including two-phase clock signals (GCK1, GCK3) that are provided to odd-order stages and two-phase clock signals (GCK2, GCK4) that are provided to even-order stages, of which phases are shifted by 90 degrees from each other. |
