Scanning signal line drive circuit and display device equipped with same

A scanning signal line drive circuit to drive a plurality of scanning signal lines arranged in a display of a display device, the scanning signal line drive circuit including a shift register including a plurality of unit circuits configured to operate based on a plurality of clock signals, wherein

• at least a first non-selection level voltage and a second non-selection level voltage are provided to each unit circuit, as a non-selection level voltage having a voltage level that brings the scanning signal lines into a non-selected state,
• each unit circuit includes:
• a first output node configured to output a first output signal to be provided to a corresponding scanning signal line;
• a first-output-node stabilization transistor having a control terminal, a first conduction terminal connected to the first output node, and a second conduction terminal to which the first non-selection level voltage is provided;
• a non-selection control transistor having a control terminal, a first conduction terminal connected to the first output node, and a second conduction terminal to which the second non-selection level voltage is provided;
• and
• a second output node configured to output a second output signal to control operation of a different shift register,
• the plurality of unit circuits sequentially output, as the first output signal, selection level voltages having a voltage level that brings the scanning signal lines into a selected state, from the first output node,
• a difference in voltage level between the selection level voltage and the second non-selection level voltage is larger than a difference in voltage level between the selection level voltage and the first non-selection level voltage, and
• in each unit circuit, upon changing a corresponding scanning signal line from a selected state to a non-selected state, the non-selection control transistor is brought into an on state and then the first-output-node stabilization transistor is brought into an on state.
