Summary:The utility model provides a shift register, an array substrate grid drive unit, and a display apparatus, used for solving two problems: first, the grid output terminal of the conventional shift register can not keep the ineffective state, thereby leading to faulty operation; second, the threshold-voltage of a film transistor rises, thereby shortening the service lifetime of the shift register. The shift register of the utility model comprises a pull-up module, a pull-up drive module, a first pull-down module, a pull-down drive module, and a second pull-down module. The shift register can prevent the suspension of the grid output terminal in the ineffective state and avoid the influence from noise voltage, thereby making the shift register reliably keep the ineffective state. Moreover, the alternation of two pull-down modules makes the grid output terminal in the ineffective state in low level, thereby avoiding the incident that some transistor keeps working while the grid output terminal is in the ineffectiv
