Shift register, gate drive circuit and display panel

The utility model discloses a shift register, a gate drive circuit and a display panel, a second output control module comprises a first control unit, and the first control unit comprises a first control subunit and a second control subunit. Therefore, even if the threshold voltage of a transistor in the first control subunit is positively biased and the leakage current of the transistor is relatively large, due to the existence of the second control subunit, the second control subunit plays a certain role in cutting off between a second node and the first control subunit, so that the electric leakage of the potential of the second node through the first control subunit is reduced, and the reliability of the device is improved. Therefore, the potential of the second node can be kept stable, the stability of the output signal of the shift register is ensured, and the display quality is improved. 本实用新型公开了一种移位寄存器、栅极驱动电路和显示面板，通过设置第二输出控制模块包括第一控制单元，第一控制单元包括第一控制子单元和第二控制子单元，因此即使第一控制子单元中的晶体管阈值电压正偏导致其自身漏电流较大，由于第二控制子单元的
