Each driver circuit in this shift register comprises an output section, a precharge section, a voltage-increasing section, a gate-voltage discharge section, a gate-wire discharge section, and internal wiring (netA). The output section contains a TFT (F) that outputs a selection voltage to a gate wire. The precharge section contains a TFT (B) that outputs a control voltage that operates the TFT in the output section. The voltage-increasing section increases the gate voltage of the TFT in the output section via a capacitor (Cbst). The gate-voltage discharge section contains a TFT (K) that lowers said gate voltage during a period during which the gate wire is not selected. The gate-wire discharge section contains a TFT (L) that outputs a non-selection voltage to the gate wire during said period. The internal wiring is connected to the gate terminal of the TFT in the output section, the precharge section, the gate-voltage discharge section, and the voltage-increasing section. The gate terminal of at least one of the TFTs in the precharge section, the gate-voltage discharge section, and the gate-wire discharge section is connected to the internal wiring in another driver circuit. |
