Abstract

A GOA driving circuit (100), a display panel (1) and a display device. The GOA driving circuit (100) includes multiple cascaded GOA units (110), each GOA unit (110) includes a trigger circuit (10), an inverter circuit (20), a pull-up circuit (30) and a pull-down circuit (40). The inverter circuit (20) includes a first thin film transistor (T1) and a second thin film transistor (T2). When a first clock signal (CKL) is at a high level, the trigger circuit (10) and the first thin film transistor (T1) are switched on. When an output of the trigger circuit (10) is at a high level, voltages at two ends of the second thin film transistor (T2) are both at a high level and a through current of the second thin film transistor (T2) is small. When the first clock signal (CKL) is at a low level, the first thin film transistor (T1) is switched off, then the second thin film transistor (T2) is also unable to form the through current.
