Shift register unit, gate drive circuit and display panel

The invention relates to the technical field of display, and provides a shift register unit, a gate drive circuit and a display panel. The shift register unit comprises a first shift register circuit and a second shift register circuit, the first shift register circuit is connected with a signal end group and a first output end, and the first shift register circuit is used for outputting a first shift signal to the first output end in response to a signal of the signal end group; the second shift register circuit is connected with the first shift register circuit, the second shift register circuit is connected with the signal end group and a second output end, and the second shift register circuit is used for responding to the signal of the signal end group and outputting a second shift signal to the second output end; and the effective level of the first shift signal and the effective level of the second shift signal are logically opposite. According to the display panel, the driving of the gate driving circ
