PROBLEM TO BE SOLVED: To provide a display device capable of maintaining an appropriate output to a scanning signal line even when a threshold shift occurs in the transistor of a drive circuit.SOLUTION: A circuit block (310) of the drive circuit of a display device comprises: a first transistor (T5) having a gate to which a first node (N1) which is turned into an active potential in an output period including a period in which an active potential is applied to a corresponding scanning signal line is connected, the first transistor (T5) controlling the conduction of a first clock signal line to which a first clock signal is applied and the scanning signal line; a second transistor (T2) having a gate to which a second node (N2) which is turned into an active potential in a non-output period as a period other than the output period is connected, the second transistor (T2) controlling the conduction of the first node and an inactive potential line fixed to an inactive potential; and a third transistor (T4) having a gate to which the first node is connected, the third transistor (T4) controlling the conduction of the second node and a first periodic signal line to which a first periodic signal (Vn+4) which is turned into the active potential in the end of the output period is applied. |
